Since both ppc and ppc64 have LE variants which are now reported by uname,
add that flag (__AUDIT_ARCH_LE) to syscall_get_arch() and add
AUDIT_ARCH_PPC64LE variant.

Without this,  perf trace and auditctl fail.

Mainline kernel reports ppc64le (per a058801) but there is no matching
AUDIT_ARCH_PPC64LE.

Since 32-bit PPC LE is not supported by audit, don't advertise it in
AUDIT_ARCH_PPC* variants.

The audit changes look fine to me, but as I mentioned earlier, this should go 
in via the ppc tree and not the audit tree.

Thanks.

Yep I'll take it via the powerpc tree, I'll CC stable as well as presumably we
want this to work in all versions that had LE support.

Yes, please!

(I was very tempted to change the #error to #warning, but figured the
placeholder comment in the uapi file was sufficient.)

cheers
