* config.make.in (fno-unit-at-a-time): Define.
* configure.in: Add test for -fno-unit-at-a-time. Fix text for -fpie. * csu/Makefile (CFLAGS-initfini.s): Add $(fno_unit_at_a_time). * locale/Makefile (CFLAGS-loadlocale.c): Likewise. For linuxthreads: * Makefile (CFLAGS-pt-initfini.s): Add $(fno_unit_at_a_time). * sysdeps/unix/sysv/linux/x86_64/Makefile (CFLAGS-pt-initfini.s): Likewise. For nptl: * Makefile (CFLAGS-pt-initfini.s): Add $(fno_unit_at_a_time). * sysdeps/unix/sysv/linux/x86_64/Makefile (CFLAGS-pt-initfini.s): Likewise.
