MIPS EABI is a bare-metal ABI so remove it.
Also fix uClibc to really work with N32 ABI, which used the EABI knob
previously.

The FLAT (Separate Data) and FLAT Shared ABIs are rarely used, and the
FLAT Shared ABI requires the user to manually assign an unique ID to
each shared library, which we will never support in
Buildroot. Therefore, restrict ourselves to FLAT and FDPIC.
In addition to this, ensure that when FLAT is selected, only static
libraries are produced, because this is what FLAT supports. It will
fix problems such as
http://autobuild.buildroot.org/results/2d756d75162e8737e99df8189bde93ed1a09feef/build-end.log.
Moreover, we make FDPIC the default ABI, since if someone is using
Buildroot, it's most likely to generate a fairly elaborate embedded
Linux system, on which shared libraries are probably useful.

So, the "n64" argument coming from buildroot should be changed to "64"
so that gcc's ./configure step does not error out.

With the Sourcery CodeBench IA32/AMD64 toolchain, the proper -march=

Add the ability for buildroot to build an SPE ABI enabled toolchain.
This is mandatory for e500v1/v2 cores since they don't support classic
FPU mode as the e500mc does.
Useful for Freescale's PowerQUICC III and single/dual-core QorIQ
line of processors.
The new TARGET_ABI variable is used rather than TARGET_CFLAGS for
uclibc's UCLIBC_EXTRA_CFLAGS to avoid breakish CFLAGS leaking in, a
good example being -mthumb for ARM.

sh2eb and sh2a_nofpueb gnuconfig targets are no longer supported

To build for devices without an fpu, the relevant toolchain flags
will have to be specified.

The Alpha, CRIS, IA64 and Sparc64 architectures have been marked as

The CRIS architecture support in Buildroot hasn't been updated since a
long time. Even a toolchain with recent kernel headers does not build
due to missing patches.
Moreover, the CRIS architecture has been discontinued by Axis, as
visible at http://www.axis.com/products/dev/index.htm. We will remove
it from Buildroot at the next release cycle.

Those architectures don't exist anymore (Alpha, IA64) or aren't widely
used for embedded systems running Linux. Moreover, no clear Buildroot
maintainer has stepped in to maintain these architectures, so it's
better to not pretend that we support them.
The goal is to mark them as deprecated in 2010.08 and remove them in
2010.11.

This commit solves bug #1051. The problem in this bug in that WebKit
compiles a sample C program, which uses WebKit. As WebKit is written
in C++, even though the program it built with CROSS-gcc, it must be
linked with libstdc++. However, CROSS-gcc can't find the libstdc++ has
it's hidden inside <sysroot>/<tuple>/lib.
Therefore, this commit creates a symbolic link <sysroot>/<tuple>/lib
-> <sysroot>/lib before running the CROSS-gcc installation. While this
may look like a hack, this is the solution used by both Crosstool-NG
and OpenWRT.
Moreover, with this symbolic link in place, I think bug #1741 may also
be solved. The problem in this bug is that the linker tries to link
against /lib/libc.so.0. This is due to the fact that the linker finds
a libc.so script file in the original toolchain location and not
inside the copy of the toolchain sysroot in $(STAGING_DIR). As the
script file is found outside of the current toolchain sysroot, ld
considers the script has non-sysrooted, and therefore doesn't prefix
all paths found in the script file (such as /lib/libc.so.0) with the
sysroot path, leading to the failure.
So, in details, this commit :
* Adds a BR2_ARCH_IS_64 invisible config knob that is used to know if
the arch is a 64 bits architecture or not.
* Creates the <sysroot>/<tuple>/lib -> <sysroot>/lib symbolic link,
and the <sysroot>/<tuple>/lib64 -> <sysroot>/lib64 symbolic link if
needed.
* Fixes the external toolchain sysroot detection code so that the
'sed' replacement is done *after* the readlink -f evaluation.
I have tested this by building ARM, x86 and x86_64 toolchains with
Buildroot, and then use these toolchains as external toolchains to
build a full X.org/Gtk/WebKit/Midori stack. I have also done a
complete ARM Buildroot internal toolchain build with the same full
X.org/Gtk/WebKit/Midori stack.
