From 6e2556963d523ecef9a2a6130c899d146a3b7333 Mon Sep 17 00:00:00 2001 From: Stijn Tintel Date: Tue, 22 Sep 2020 14:02:58 +0300 Subject: toolchain/gcc: use ELFv2 ABI on ppc64 with musl At configuration time, gcc assumes that ppc64be targets use the ELFv1 ABI, and ppc64le targets use the ELFv2 ABI. However, musl libc does not support the ELFv1 ABI on ppc64 at all, regardless of the endianness. Therefore, when building for a ppc64 arch and with musl libc, instruct gcc to use the ELFv2 ABI. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93157 for more info.
