minor portability patches

["Peter O'Gorman" <gdb-patches at mlists dot thewrittenword dot com>]

Hi,

We just built gdb-7.2 and had a couple of minor issues.

Patches attached, some I am less sure about than others.

When we build --with-python, IRIX 6.5 needed -lpthread, I don't know if
this is the correct place to add that though.

__FUNCTION__ is a gccism.

AIX 6.1 does prototype getthrds in /usr/include/procinfo.h, though not
identically to gdb's prototype, it has these:
extern  int     getthrds( pid_t, void *, int, tid_t *, int );
extern  int     getthrds64( pid_t, void *, int, tid64_t *, int );

Also avoid some warnings on AIX about ptrace32's third argument.

-rdynamic was being added regardless, causing link failures on multiple
platforms.

At least solaris cc complained about returning from void functions.

Thanks,
Peter
