* In toolchain/external-toolchain/ext-tool.mk, copy the contents of
the sysroot directory to the staging dir.
* In package/Makefile.in, add a --sysroot CFLAGS pointing to the
staging dir
* Remove the CFLAGS and LDFLAGS definition from
TARGET_CONFIGURE_OPTS. I haven't investigated exactly why, but with
these options, DirectFB fails to build because it cannot find
PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP, even if DirectFB's Makefile
properly sets -D_GNU_SOURCE.
I have already sent this patch on December, 2nd to the mailing-list,
but got no feedback. So let's commit and see what happens :-)

The following changes allow for use of a central configure cache
file. This speeds up configuration of packages.
Its use is configurable at the top level (BR2_CONFIG_CACHE - default n).
Old style makefiles can use it if they use the following MACRO in makefiles:
$(AUTO_CONFIGURE_TARGET) see my change to directfb.mk.
New style Autotools.in will use it if you set the global option.
However you can enable the global option and on a per package overrule it by doing
the following: $(PKGNAME)_USE_CONFIG_CACHE = NO see fontconfig.mk for an example
of this.
Finally I have removed a few config variable settings which indicated no CXX compiler
as this is wrong and breaks the build when using this central cache.

I would appreciate feedback on this change (I have been testing for 2-3 weeks)
But I can never test all cases! If you enable the BR2_CONFIG_CACHE option some
Makefile.autotools.in based packages may now break - I cannot build them all.
In this case you may need to remove config options that are being hardcoded all
over the place (like gtk saying we have 2 CXX compiler) or disable the use
of CONFIG CACHE file like I have done in fontconfig.
I can build all packages required to get WebKit on DirectFB up and running
and it runs fine.
I will try to resolve any issues this creates as fast as I can.

This patch is a new version of a patch already sent several times on
the mailing-list, committed and reverted a few times by Daniel Laird,
due to several imperfections. This version is a new try at finding a
solution that works for everybody. Hopefully it'll work :-)
The original problem is that external toolchain builds failed because
packages couldn't find their dependent libraries at configure time and
could not be linked with them. To fix these two problems, two things
are added:
* The TARGET_LDFLAGS variable was exposed as LDFLAGS at ./configure
time thanks to TARGET_CONFIGURE_OPTS. The TARGET_LDFLAGS variable
contains -L options with the path in the STAGING_DIR for the
libraries. It allows ./configure scripts to properly compile the
small test programs testing whether a dependency is properly
installed.
* The TARGET_CFLAGS contains a new -Wl,--rpath-link option for both
$(STAGING_DIR)/lib and $(STAGING_DIR)/usr/lib. It allows library
depending on other libraries to link properly. The TARGET_CFLAGS is
exposed as CFLAGS in TARGET_CONFIGURE_OPTS.
This new version fixes a problem encountered by hartleys
<hartleys@visionengravers.com> when building the kernel. The problem
was that the -Wl,--rpath-link options were added to LDFLAGS, while
there are options for the C compiler, not the ld linker. Moving them
to CFLAGS seems to fix the issue.

Revert the rpath patch, it looked good up until someone tried
to build a kernel as well. This seems to break as a result.
Will post a new patch soon and see how that goes..

Apply the patch I posted some time ago that fixes
rpath issues with external toolchains.
Has been tested by users of buildroot and feedback looks good.

As per various email discussions add -rpath-link
to the LDFLAGS.
This definately fixes a few issues for Thomas and myself
Any objections and it can be pulled again.

Upgrade to pkgconfig 0.23 which has native sysroot support (buggy,
but easily fixable), which allows us to get rid of pkgconfig-filter.sh.
At the same time cleanup the makefile.
Packages that need to pass additional CFLAGS in their .mk have to do something
like this: ...configure $(foreach i,$(foo_CFLAGS),CFLAGS+=$$i) --prefix=...
Will need to try to copy eventual pre-existing project-specific deps back
to package/config in order not to mess up the corresponding timestamps (to avoid superfluous rebuilds)..
quite work yet for me, but this clearly is a huge project and not having it
quite work on the first pass is hardly unexpected. We definately want this
stuff in buildroot.
