Re: Build problem on ppc64be + musl

I believe that some OS (FreeBSD? NetBSD?) is trying to use ELFv2 with PPC64 BE. That is a separate issue and I do not believe that Musl Libc plans to support that configuration. AIX continues to use its ABI, which essentially is closely related to ELFv1 and uses the XCOFF file format and syntax.

Re: Build problem on ppc64be + musl

Forcing ELFv2 abi doesn't work for big-endian mode as this mode has no support for ELFv2. ppc64 linux big-endian is deprecated, it' not unexpected to get such issues. Dropping big-endian support for powerpc could be an option to solve this issue but that will be a drawback for AIX (BE) systems.
