from gcc should be disabled, otherwise, the build of gcc fails.

For some reason (probably because the ARC changes modify some lex/yacc
files without updating their pre-generated variants, or because the
date/time of the pre-generated files is not correct), building the ARC
gcc requires host-flex and host-bison.
We have tested 4.2 for AVR, 4.3 and 4.4 for ARM, and none of those
need host-flex or host-bison to be installed, so only the 4.4 for ARC
seems to be affected.
Fixes the build failure visible at

Since gcc doesn't use the package infrastructure, it doesn't get all
the good generic environment variables, and forgets to get
$(HOST_DIR)/usr/bin in its PATH. This prevents gcc from finding and
using host tools built by Buildroot.
This patch therefore ensures that $(HOST_MAKE_ENV) or
$(TARGET_MAKE_ENV) are passed at the appropriate locations. It will be
useful for a later patch that makes gcc depend on host-flex/host-bison
in some situations.

When a FOO_SITE variable ends in a slash and gets joined with a

has a double slash. While double-slashes are fine in unix paths, they
are reserved in URIs - the part following '//' must be an authority.

Note however that these cores are v4 and NOT v4t.
* Make the sa110 & sa1110 cores -> strongarm since they're the same.
* Drop all of the ARM variants lower than v4 including generic, there's
no point in supporting obsolete targets.

For each version of gcc, we need to check whether it requires mpc as a
dependency. Since this is true for 4.5, 4.6, 4.7, snapshots and now
4.8, let's factorize this code a bit by using a Kconfig symbol that
tells us whether we are using a gcc version that requires mpc.

As discussed during the ELCE 2012 Buildroot Developers Meeting, we no
longer want to support the possibility of building a toolchain for the
target. None of the core developers have any use for this, it has been
known to be broken or cause problems for a long time without anyone
providing fixes for it.
In addition to this, Buildroot is inherently a cross-compilation tool,
so the usage of a native toolchain on the target is not really
useful. Many newcomers are tempted to use this possibility even though
it is clearly not the intended usage of Buildroot.

Xtensa is a configurable processor architecture, which allows to define
additional instructions and registers. The required variant specific
information for the toolchain is delivered in an 'overlay' file, which
needs to be 'untarred' to the corresponding directories after the
source is installed and patched.
This patch provides support for binutils, gcc, and gdb with a very
limited changes to the build scripts. These additions are only executed
for the Xtensa architecture and have no effect on other architectures.

Variant'].

As stated in commit 555c2585bf, the
Xtensa architecture has been introduced in 2009 and never changed
since its initial introduction. It requires some special handling that
is a bit annoying, and despite our call to the initial developers, and
the announcement of the deprecation of the architecture during the
2012.05, nothing has happened. Therefore, drop support for this
architecture.
