elf/Makefile: Run IFUNC tests if binutils supports IFUNC
We should run IFUNC tests with --disable-multi-arch if the toolchain supports IFUNCs. For correctness, --disable-multi-arch must not remove IFUNC support from the loader. Tested on x86-64, x32 and i686 with and without --disable-multi-arch. * configure.ac (have-ifunc): New LIBC_CONFIG_VAR. * configure: Regenerated. * elf/Makefile: Run IFUNC tests if binutils supports IFUNC. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
