+Subject: [PATCH] crypto/perlasm/ppc-xlate.pl: add linux64v2 flavour
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
