[PATCH] solib_global_lookup: Fetch arch from objfile.

[Doug Evans <xdje42@gmail.com>]

Hi.

solib_global_lookup should be using the objfile's arch,
not fetching it from global state.

Regression tested on amd64-linux.

2014-10-31  Doug Evans  <xdje42@gmail.com>

	* objfiles.c (get_objfile_arch): Constify.
	* objfiles.h (get_objfile_arch): Update prototype.
	* solib.c (solib_global_lookup): Fetch arch from objfile,
	not target_gdbarch.
