[commit/hppa/multiarch] multi-arch PC_IN_SIGTRAMP

[Joel Brobecker <brobecker at gnat dot com>]

There was another change that I forgot to commit last I was working
on this (I forgot it because I am doing several changes at the same
time before lauching a round of testing - then proceeded to split
the change into separate patches, but got interrupted in the middle).

Anyway, here is the ChangeLog, and the patch:

2003-06-05  J. Brobecker  <brobecker@gnat.com>

        * hppa-hpux-tdep.c (hppa_hpux_init_abi): New function, setting
        pc_in_sigtramp multiarch method.
        (hppa_hpux_som_init_abi): Use it.
        (hppa_hpux_elf_init_abi): Likewise.
        * config/pa/tm-hppah.h (PC_IN_SIGTRAMP): Remove, now that this
        macro has been multiarched.
        * config/pa/tm-hppa64.h (PC_IN_SIGTRAMP): Temporarily set this
        macro here, as hppa64 isn't multiarched yet.

Tested on hppa-hpux11.  Checked in.

It's still all boring stuff, but we are getting closer to more
interesting reorganizational changes... I wish I had more time to
dedicate to this.
