Integrate gcc 3.4.2 and add patches from both openembedded (6??-*)

Browse Source 
and Dan Kegel's crosstools (7??-*).
Use makefile vars for toolchain names in ccache.mk and gdb.mk.
Fix a g++-related symlink issue with ccache.
Change the default to gcc 3.4.2 and binutils 2.15.91.0.2 (now that mips
is building).  Let the users go forth and test...  ;-)

Here is a patch for the first possibility.
It certainly makes libstdc++.so to link and even the unwind info looks
good on brief skimming.

This means that the unknown character is no longer ignored, despite the
comment. As a side effect a line starting with a line comment character
not followed by APP in NO_APP mode now triggers an error instead of just a
warning, breaking builds of glibc on m68k-linux. Earlier in
read_a_source_file where #APP is handled there is another comment that
claims that unknown comments are ignored, when in fact they aren't (only
the initial line comment character is skipped).
Note that the presence of #APP will mess up the line counters, but
that appears to be difficult to fix.

Atsushi Nemoto <anemo@mba.ocn.ne.jp> writes:
>/ Is this a get_user's problem or gcc's?/
The latter. gcc is putting the empty asm:
__asm__ ("":"=r" (__gu_val));
into the delay slot of the call.
Part of the problem is that gcc estimates the length of an asm to be the
number of instruction separators + 1. This means that it estimates the
asm above to be one instruction long, which is perhaps a little silly
for an empty string.
But the real problem is that gcc should never trust this estimate anyway,
since each "instruction" could obviously be a multi-instruction macro.
gcc should certainly never put asms into delay slots.
FWIW, I don't think the bug is specific to 3.3 or 3.4. It could
probably trigger for other gcc versions too. It is highly dependent
on scheduling though.
The attached 3.4.x patch fixes the problem there, but if you want to work
around it for old versions, just avoid using empty asms if you can,
or make them volatile if you can't.
Of course, the problem isn't confined to empty asms. If you have an asm
with a single, multi-instruction macro, gcc might try putting that in a
delay slot too. You should at least get an assembler warning in that case.

in gcc/config/arm/linux-elf.h.
#
# Submitted:
#
# Dimitry Andric <dimitry@andric.com>, 2004-05-01
#
# Description:
#
# Nicholas Pitre released this patch for gcc soft-float support here:
# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
#
# This version has been adapted to work with gcc 3.4.0.
#
# The original patch doesn't distinguish between softfpa and softvfp modes
# in the way Nicholas Pitre probably meant. His description is:
#
# "Default is to use APCS-32 mode with soft-vfp. The old Linux default for
# floats can be achieved with -mhard-float or with the configure
# --with-float=hard option. If -msoft-float or --with-float=soft is used then
# software float support will be used just like the default but with the legacy
# big endian word ordering for double float representation instead."
#
# Which means the following:
#
# * If you compile without -mhard-float or -msoft-float, you should get
# software floating point, using the VFP format. The produced object file
# should have these flags in its header:
#
# private flags = 600: [APCS-32] [VFP float format] [software FP]
#
# * If you compile with -mhard-float, you should get hardware floating point,
# which always uses the FPA format. Object file header flags should be:
#
# private flags = 0: [APCS-32] [FPA float format]
#
# * If you compile with -msoft-float, you should get software floating point,
# using the FPA format. This is done for compatibility reasons with many
# existing distributions. Object file header flags should be:
#
# private flags = 200: [APCS-32] [FPA float format] [software FP]
#
# The original patch from Nicholas Pitre contained the following constructs:
#
# #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
# %{mhard-float:-mfpu=fpa} \
# %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
#
# However, gcc doesn't accept this ";:" notation, used in the 3rd line. This
# is probably the reason Robert Schwebel modified it to:
#
# #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
# %{mhard-float:-mfpu=fpa} \
# %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
#
# But this causes the following behaviour:
#
# * If you compile without -mhard-float or -msoft-float, the compiler generates
# software floating point instructions, but *nothing* is passed to the
# assembler, which results in an object file which has flags:
#
# private flags = 0: [APCS-32] [FPA float format]
#
# This is not correct!
#
# * If you compile with -mhard-float, the compiler generates hardware floating
# point instructions, and passes "-mfpu=fpa" to the assembler, which results
# in an object file which has the same flags as in the previous item, but now
# those *are* correct.
#
# * If you compile with -msoft-float, the compiler generates software floating
# point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
# order) to the assembler, which results in an object file with flags:
#
# private flags = 600: [APCS-32] [VFP float format] [software FP]
#
# This is not correct, because the last "-mfpu=" option on the assembler
# command line determines the actual FPU convention used (which should be FPA
# in this case).
#
# Therefore, I modified this patch to get the desired behaviour. Every
# instance of the notation:
#
# %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
#
# was changed to:
#
# %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
#
# I also did the following:
#
# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
# be consistent with Nicholas' original patch.
# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
# macros I could find. I think that if you compile without any options, you
# would like to get the defaults. :)
# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
# anymore. (The required functions are now in libgcc.)
