Support compilers defaulting to PIE
If PIE is the default, we need to build programs as PIE.

	[BZ #17841]
	* Makeconfig (no-pie-ldflag): New.
	(+link): Set to $(+link-pie) if default to PIE.
	(+link-tests): Set to $(+link-pie-tests) if default to PIE.
	* config.make.in (build-pie-default): New.
	* configure.ac (libc_cv_pie_default): New.  Set to yes if -fPIE
	is default.  AC_SUBST.
	* configure: Regenerated.
	* elf/Makefile (LDFLAGS-tst-dlopen-aout): New.
