Sorry, I should have chimed in when I saw Nick's message yesterday.  The
same issue is present for 64-bit hppa targets.  See code in elf-hppa.h.

So, I think I want to move the search into a separate function in elf-hppa.h
as is done on bfin and frv.  I tested this change on linux and was just
about to test it on hppa64-hp-hpux11.
