Commit 8d929f4b ("toolchain/gcc: Only enable --with-float when it makes
sense") restricted the --with-float use to only MIPS, ARM and SPARC,
while it seems that powerpc needs it as well.
Fixes the qemu_ppc_virtex_ml507_defconfig build.

For ARC, libgcc is always included, even when -nostdlib is given. This is
related to some small pieces of code that are not always generated by the
compiler; a call to libgcc is used in those cases instead.
During the initial stages of building the toolchain, this is a problem, as
libgcc does not exist yet. The ARC compiler supports -really-nostdlib to
override the default behavior.

When a FOO_SITE variable ends in a slash and gets joined with a
FOO_SOURCE variable like $(FOO_SITE)/$(FOO_SOURCE), the resulting URI
has a double slash. While double-slashes are fine in unix paths, they
are reserved in URIs - the part following '//' must be an authority.

The x86/x86-64 CodeSourcery toolchains use some weird locations for
the gdbserver binary:
$ find . -name 'gdbserver'
./i686-pc-linux-gnu/libc/atom/usr/bin/gdbserver
./i686-pc-linux-gnu/libc/atom/usr/lib/bin/gdbserver
./i686-pc-linux-gnu/libc/core2/usr/bin/gdbserver
./i686-pc-linux-gnu/libc/core2/usr/lib64/bin/gdbserver
./i686-pc-linux-gnu/libc/usr/lib/bin/gdbserver
./i686-pc-linux-gnu/libc/usr/lib64/bin/gdbserver
Notice that it's sometimes hidden in a usr/{lib,lib64}/bin
directory. This patch changes the gdbserver logic to also try in this
location.

This commit converts gdb to the package infrastructure, and therefore
moves it from toolchain/gdb to package/gdb.
The target package is now visible in "Package selection for the
target" => "Debugging, profiling and benchmark". The main option,
"gdb", forcefully selects the "gdbserver" sub-option by
default. Another sub-option, "full debugger" allows to install the
complete gdb on the target. When this option is enabled, then
"gdbserver" is no longer forcefully selected. This ensures that at
least gdbserver or the full debugger gets built/installed, so that the
package is not a no-op.
The host debugger is still enabled through a configuration option in
"Toolchain". It is now visible regardless of the toolchain type (it
used to be hidden for External Toolchains). The configuration options
relative to the host debugger are now in package/gdb/Config.in.host,
similar to how we have package/binutils/Config.in.host.
Since gdb is now a proper package, it is no longer allowed to 'select
BR2_PTHREADS_DEBUG' to ensure thread debugging is available when
needed. Instead, it now 'depends on
BR2_TOOLCHAIN_HAS_THREADS_DEBUG'. This option, in turn, is selected by
the different toolchain backends when appropriate. The
'BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED' option is removed, since
we no longer need to know when it is allowed to 'select
BR2_PTHREADS_DEBUG'. Also, the 'BR2_PTHREADS_DEBUG' option is moved to
appear right below the thread implementation selection (in the case of
the Buildroot toolchain backend).

* Add Faraday FA526/626 as suggested on bug #1291
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.
* Fix uClibc USE_BX logic, it was always on, this would break the new

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.

Previously, the crosstool-NG backend did depend on the top-level
Buildroot's .config to detect changes in the toolchain options,
using a tentatively-clever heuristic, which also included the full
Buildroot's version string to push down to set the components' versions
strings.
In doing so, any commit in the Buildroot tree would imply a complete
rebuild of the toolchain, even in the case the toolchain options did
not change, thus being a large annoyance (to say the least).
As Buildroot never guaranteed that toolchain options would be detected,
even less handled, and that the internal backend does neither detect nor
act on toolchain options changes, and delegate that to the user, there
is no point in individualising the crosstool-NG backend's behaviour.
This reasoning also applies to the depdency on the crosstool-NG's bundled
.config file, too.
So, just drop the not-so-clever heuristic, and just build the toolchain
once, leaving to the user the responsibility to explictly ask Buildroot
to rebuild the toolchain.

The existing Microblaze toolchains that we have have the annoying
property of being based on a very old glibc version: 2.3.6. Xilinx
provides newer toolchains with glibc 2.14, generated by Crosstool-NG,
but they are only available as part of a huge Git repository that
contains the gcc, Linux, binutils, glibc sources unpacked (4.4 GB
total), which makes is very unpractical.
I contacted the Xilinx person who did those toolchains, but they
apparently didn't intend to change that anytime soon.
So, we have created a tarball for those toolchains, adding a
README.txt file in the tarball that points back to the original
location that contains the source code for them. Those tarballs are
hosted on sources.buildroot.net.
This commit then adds support for those two new external toolchains,
one for little endian Microblaze, another one for big endian
Microblaze.
