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_PPC*LE variants. Without this, perf trace and auditctl fail. Mainline kernel reports ppc64le (per a058801) but there is no matching AUDIT_ARCH_PPC64LE.
