gcc-3.4.0-glibc-2.2.5 barfs with a few undefined refereces and multiple
definitions. The follwing patch seems to take care of the undefined
reference of __dl_runtime_resolve symbol.

See http://sources.redhat.com/ml/libc-alpha/2002-02/msg00091.html
See also glibc-2.2.5-mips-build-gmon.patch, which takes care of the other part of this for mips.

ChangeLog:
        sysdeps/mips/dl-machine.h (elf_machine_matches_host): Use
        __attribute_used__.
        (__dl_runtime_resolve): Likewise.

Fixes error
