Silence compiler warning on

[Mark Kettenis <mark.kettenis@xs4all.nl>]

Right now, when I compile BFD on HP-UX 10.20, I get the following
warning (wich is fatal because of -Werror):

/export/jive/kettenis/src/gdb/bfd/bfd.c: In function `_bfd_abort':
/export/jive/kettenis/src/gdb/bfd/bfd.c:801: warning: `noreturn' function does return

The problem here is that the system headers don't declare _exit() with
__attribute__((noreturn).  Previously we didn't get this warning
because _bfd_abort() called xexit(), which was declared with
__attribute__((noreturn)) (and xexit.c was compiled without -Werror).

The attached patch is an attempt to fix this.  Ok?
