Blackfin FD-PIC patch 3/6.

Change _dl_find_hash to _dl_lookup_hash, as on the NPTL branch.
_dl_find_hash is now a wrapper function around it; unlike on the NPTL branch,
it retains the old interface so that not all callers need to be changed.

_dl_lookup_hash can optionally give its caller a pointer to the module where
the symbol was found.

Introduce ELF_RTYPE_CLASS_DLSYM for lookups from libdl.

Spelling fixes in the Blackfin port, since Alex Oliva's original version of
these patches used _dl_find_hash_mod as the name of the function rather than
_dl_lookup_hash.
