[commit] Fix build failure on sparc-solaris

[Joel Brobecker]

I applied the following change.  It's a modified version of DanielG's
change where I removed the check for UNIXWARE since, as far as I could
tell from the configure script, NEW_PROC_API implies UNIXWARE:

  case "${host}" in
  *-*-unixware* | *-*-sysv4.2* | *-*-sysv5* | *-*-interix* )
      AC_DEFINE(NEW_PROC_API, 1,

I tried to confirm that the change was appropriate for platforms
that configure as *-*-sysv4.2* | *-*-sysv5*, but I couldn't find
a specification of SVR4 that included procfs.  Perhaps this is not
part of the API, or even part of SVR4 altogether.

A look at config.guess did not help much in getting full confidence
in the patch.  IMO, I think that the correct way of handling this
would be to use the same #ifdef as BFD which conditions the definition
of elfcore_write_prstatus (IOW: HAVE_PRSTATUS_T). However, I'm just
as happy to see if relying on NEW_PROC_API is good enough in practice.
I can work on improving the situation if/when a problem is reported.

This is why I decided to approve and apply this patch.

gdb/ChangeLog:

        * procfs.c: (procfs_do_thread_registers) Use elfcore_write_lwpstatus.
