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.

     4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch

     5 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,

     6 you have to actually list out the multilibs you want or you will end up with

     7 just one when using targets like 'sh4-linux-gnu'.

     8 

     9 The resulting toolchain can't even build a kernel as the kernel needs to build

    10 with the nofpu flag to be sure that no fpu ops are generated.

    11 

    12 Here we restore the gcc-3.x behavior; the additional overhead of building all

    13 of these multilibs by default is negligible.
