I thought I'd provided that information already. Should I attach the
preprocessed .s file?

This is a static-only build, as the later GCC build will be built with a
static libgcc. (I'm also using --with-pic, but the same failures result
without that.)

Interestingly, a shared-only build passes all tests.

I just see an invocation of plain "as" in there. If the problem is
down to the linker, however, this would be the only instance of it
that I'm aware of.

Surely this is something simple enough! Would you want to see assembly
from one of the generic .c files?

Okay, good to know that's an option.
