tools/gold/X86/split-dwarf.ll test fails on 32-bit arm with SIGBUS #62196

The tools/gold/X86/split-dwarf.ll test seems to fail on 32-bit arm with SIGBUS (bus error) (tested at commit 0be1fbac2a7797399c0970e3f4033288036b65f6):

This looks like an issue in gold so maybe we should just stop building the gold bits on arm in Gentoo, given gold isn't getting much maintenance in binutils right now.

thesamesam commented 1 year ago

Yeah, I think we can call this a gold bug.
