arch/powerpc: add powerpc64le support

Technically, I don't forbid powerpcle support either, but I'm not sure that
there is any library/compiler support for that at the moment (though the hw
technically makes it possible).

powerpc64le needs glibc 2.19 and gcc 4.9. I haven't looked into the support
tools, but at least gdb 7.5 is too old (7.7.1 definitely has support).

Also make powerpc64 non-experimental. It's practically old at this point.

The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
yann@552
     3
you have to actually list out the multilibs you want or you will end up with
yann@552
     4
just one when using targets like 'sh4-linux-gnu'.

The resulting toolchain can't even build a kernel as the kernel needs to build
yann@552
     7
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
yann@552
    10
of these multilibs by default is negligible.
