This seems to fix the minimal reproducer, but not original bug. ld still
SIGSEGVs. Bigger minimal file that still SIGSEGVs:

    // $ cat bug.i
    a() { b(); }
    __asm__(".section .gnu.warning.");
    c() { b(); }

Same steps to reproduce:
$ hppa2.0-unknown-linux-gnu-gcc         -fPIC -c bug.i -o bug.o
$ hppa2.0-unknown-linux-gnu-gcc -shared -fPIC    bug.o -o libbug.so

Will attach bigger object file as well.
