It turned out that elf32_hppa_bfd_final_link_relocate wasn't handling
undefined weak symbols correctly.  I've fixed this, the bogus error
message, and a handfull of other minor things, and commited the fixes to
pehp CVS.

Now I get
$ ld/ld-new -o tar /usr/parisc/lib/crt1.o /usr/parisc/lib/crti.o
/usr/parisc/lib/gcc-lib/hppa1.1-linux/2.9-hppa-991112/crtbegin.o
-L/usr/parisc/lib/gcc-lib/hppa1.1-linux/2.9-hppa-991112 -L/usr/parisc/lib/
rrtar.o -lgcc -lc -lgcc
/usr/parisc/lib/gcc-lib/hppa1.1-linux/2.9-hppa-991112/crtend.o
/usr/parisc/lib/crtn.o
/usr/parisc/lib//libc.a(nsswitch.o)(.data+0x64): undefined reference to
`_nss_files_getaliasent_r'

which looks like a problem with my glibc build.
