When calling ppc-xlate.pl, we pass it either linux-ppc64 or
linux-ppc64le. The script however was expecting linux64le, a result
of its OpenSSL origins. This means we aren't obeying the ppc64le
ABIv2 rules.
Fix this by checking for linux-ppc64le.
Fixes: 5ca5573820 ("crypto: vmx - comply with ABIs that specify vrsave as reserved.")

In build time vadduqm opcode is not being mapped
correctly.
Adding a new map in ppc-xlate to do this.

crypto: vmx - Fix assembler perl to use _GLOBAL
Rather than doing things by hand for global symbols to deal with
different calling conventions we already have a macro _GLOBAL in
Linux to handle this.

OpenSSL implements optimized ASM algorithms which support
VMX instructions on Power 8 CPU.
These scripts generate an endian-agnostic ASM implementation
in order to support both big and little-endian.
- aesp8-ppc.pl: implements suport for AES instructions
implemented by POWER8 processor.
- ghashp8-ppc.pl: implements support for GHASH for Power8.
- ppc-xlate.pl: ppc assembler distiller.

with the original author (Andy Polyakov <appro@openssl.org>).
