Compile archives with -fno-piehjl/pr17841/master

When compiler defaults to PIE, we compile archives with -fno-pie.   Since
archives won't be used with PIE, compile them with -fpie isn't necessary.

	[BZ #17841]
	* Makeconfig (no-pie-ccflag): New.  Set to -fno-pie.
	(pic-default): Don't define if $(no-pie-ccflag) is -fno-pie.
	(test-object-suffix): New.
	* Makerules (archive-objects): New.  Set before including
	extra-lib.mk.
	($(archive-objects)): New. New rule to append $(no-pie-ccflag)
	to CFLAGS.
	* extra-lib.mk (archive-objects): New.
	* crypt/Makefile ($(objpfx)md5test): Replace ".o" with
	$(test-object-suffix).
	($(objpfx)md5test-giant): Likewise.
	($(objpfx)sha256test): Likewise.
	($(objpfx)sha512test): Likewise.
	* math/Makefile (LDFLAGS-atest-exp): New.
	(LDFLAGS-atest-sincos): Likewise.
	(LDFLAGS-atest-exp2): Likewise.
