Support compilers defaulting to PIE
To support building glibc with GCC 6 configured with --enable-default-pie, which generates PIE by default, we need to build programs as PIE. But elf/tst-dlopen-aout must not be built as PIE since it tests dlopen on ET_EXEC file and PIE is ET_DYN. [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.
