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.
