5a6087d62e toolchain: add powerpc SPE ABI support
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.

d5247aa842 sh: Fix Buildroot sh targets to match gnuconfig targets
sh2eb and sh2a_nofpueb gnuconfig targets are no longer supported
in Buildroot. This patch replaces these Buildroot targets with sh2
and sh2a respectively, and adds sh4a targets as these are widely
used.

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

1fa6b1c276 target: default to i586 for x86
The i586 was introduced almost 20 years ago, and some software
(NPTL, libstdc++, ..) doesn't work nicely with i386 anymore, so
it is time to move on.

343f480fe2 Remove architectures marked as deprecated
The Alpha, CRIS, IA64 and Sparc64 architectures have been marked as

and/or not properly supported in Buildroot.

e5621b427c Mark CRIS architecture as deprecated
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.

a563a66347 Deprecate the Alpha, IA64 and Sparc64 support
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.

3c77bab2ee Create <tuple>/lib -> <sysroot>/lib symlink before installing cross gcc
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.
