* libhppa.h: Remove "esel" changes. Not the right approach.

* som.c: Corresponding changes.
        (som_bfd_derive_misc_symbol_info): Use ST_DATA for symbols
        which don't have a SOM symbol type associated with them.
        Reverses a 1994 change.
More PA EH tweakage (to get exception handling tables properly relocated
in shared libraries).

We used to set the symbol type based on the section this symbol
was in (ST_DATA for DATA sections, ST_CODE for CODE sections).
Strictly speaking, this is the right approach. However, the
linker chokes if we have an R_DATA_ONE_SYMBOL reloc involving
an ST_CODE symbol in a shared library, which happens for
exception handling tables.
I tried an alternate approach to generating exception handling
tables using PUSH_SYM and DATA_EXPR relocs, but that fails to
relocate exception handling tables in shared libraries.
What a pain. */
