* libhppa.h (R_HPPA_ESEL): New field selector.

Browse Source 
(e_esel): Similarly.
        * som.c (hppa_som_gen_reloc_type): If we encounter an e_esel,
        then generate R_COMP2 (PUSH_SYM), R_DATA_EXPR fixup stream.
        (som_write_fixups): Handle R_DATA_EXPR just like R_CODE_EXPR.
Making another stab at EH support on the PA.
