svn(1) diff against the ports tree
Ah, sorry, I should have known this sounded familiar... in-fact, I've solved
this once before.
devel/llvm10 needs this backported to it: https://reviews.freebsd.org/rS360875
The TL;DR is that qemu-user-static doesn't currently provide AT_EXECPATH, so
llvm runs off the end of auxv in the older versions that don't do
elf_aux_info(AT_EXECPATH, ...)
The patch attached should fix it, if brooks approves then we can go ahead and
commit it. It's still building locally, but I dont' anticipate the build to
fail given how trivial it is.
