[PATCH] bfd: Externalize the bfd_set_gp_value function

[will schmidt]

Externalize the bfd_set_gp_value function.

Hi,
  This change adds an external-visible wrapper for
the bfd_set_gp_value function.
This is a prerequisite for some gdb patches that allow
better handing of the .TOC. relocations as necessary
for the rs6000/powerpc64le target.

This patch includes updates to bfd.c to add the 
externally visible
wrapper, and the updated bfd-in2.h
as seen after rebuilding bfd with
--enable-maintainer-mode.

Credit and Thanks to Alan Modra for guidance
on what
to do and how to approach this.  That said, errors in
implementation are my own. :-)

OK for trunk?

Thanks
-Will

	* bfd/bfd.c (bfd_set_gp_value):  New external visible
	wrapper for the internal _bfd_set_gp_value function.

	* bfd/bfd-in2.h: New prototype for bfd_set_gp_value.
