crypto/perlasm/ppc-xlate.pl: add linux64v2 flavour

Browse Source 
This is a big endian ELFv2 configuration. ELFv2 was already being
used for little endian, and big endian was traditionally ELFv1
but there are practical configurations that use ELFv2 with big
endian nowadays (Adélie Linux, Void Linux, possibly Gentoo, etc.)
