This is an important distinction to make (big-endian != ELFv1, and ELFv1 != big-endian). But do note that on Linux, the musl libc (in use by distros like Alpine, Adélie, postmarketOS) only supports ELFv2, even in big-endian mode. And as the maintainer of Adélie using it as a daily-driver on an iMac G5, it's definitely something you can use (the only breakage I've seen so far on Linux is the PCRE JIT ignoring __CALL_ELF and inserting function descriptors anyway). So I wouldn't discount moving to ELFv2 ABI on BE if that is necessary to keep LLVM happy. It'd be some effort but it should work. If this is really something FreeBSD is interested in, you might even manage to convince me to put on my ports hat again, to help get the JIT patches in that are needed for upstreams that went comatose.
