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.

ARMV5 can use STRD and LDRD access instructions but these accesses need to be 
yann@1207
     5
8 byte aligned. The dynamic linker's malloc needs to match this so structures
yann@1207
     6
become 8 byte aligned to void unaligned accesses.
