Hi Stuart,
Understood. I'll try to provide as much info as needed for debugging.

Looks like it caused the compiler to ICE when configuring
mips64el-unknown-openbsd6.9/libgcc. I'm afraid it may be harder to fix.
The relevant logs look like below (full log attached):

I tried to recompile the conftest.c by adding "-v" to the compiler flag
but it didn't seem to provide anything more useful:
