2015-05-18  Andreas Tobler  <andreast@gcc.gnu.org>

gcc:
        * config/freebsd-spec.h (FBSD_STARTFILE_SPEC): Add the bits to build
	pie executables.
	(FBSD_ENDFILE_SPEC): Likewise.
	* config/i386/freebsd.h (STARTFILE_SPEC): Remove and use the one from
	config/freebsd-spec.h.
	(ENDFILE_SPEC): Likewise.

gcc/testsuite:
	* lib/target-supports.exp (check_effective_target_pie): Add *-*-freebsd*
	to the family of pie capable targets.
