Typically from .uaword directives, found in dwarf sections like .eh_frame.

It can't be avoided, at least not without disabling EH entirely.

A simple test is:

echo ".byte 0x1\n.uaword foo" | $(AS) -o foo.o && \
  readelf -r foo.o | grep R_SPARC_32

I don't have the time or knowledge to properly autoconf-ize this test
at the moment :(
