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.

     3 	* sysdeps/unix/sysv/linux/alpha/ioperm.c: force the architecture

     4 	  to ev6 in assembly code.

    13 Hrm. gcc puts .arch ev4 into the .s, and this overrides -mev6 for as.

    14 I cannot really think of anything better than
