Subject: [PATCH] crypto/perlasm/ppc-xlate.pl: add linux64v2 flavour

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.)

Subject: [PATCH] Configure: use ELFv2 ABI on some ppc64 big endian systems
|
|
|
|
If _CALL_ELF is defined to be 2, it's an ELFv2 system.
|
|
Conditionally switch to the v2 perlasm scheme.
