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.

Without this patch, the sec script that processed initfini.s removes a
yann@1201
    11
part of inlined call_gmon_start, causing undefined label errors.

This patch solves the problem by forcing gcc not to inline
yann@1201
    14
call_gmon_start with __attribute__ ((noinline)).
