Don't use lib2funcs.asm on PA

- Subject: Don't use lib2funcs.asm on PA
The only function in pa/lib2funcs.asm is __gcc_plt_call. This function
is no longer used. Thus, we don't need to build lib2funcs.asm or ensure
that __gcc_plt_call is linked into executables.
Tested with no regressions on hppa2.0w-hp-hpux11.11.

* pa/t-pa (LIB2FUNCS_EXTRA): Don't build lib2funcs.asm.
* pa/t-pro (LIB2FUNCS_EXTRA): Likewise.
* som.h (DO_GLOBAL_DTORS_BODY): Delete define.
