* hurd/hurdinit.c (map0): Remove [!PIC] conditional. cvs/libc-960616

	* shlib-versions (*-*-*): Add libutil=1.

	* rpm/Makefile (install-lib): Add libc.a et al.
	(install-others): Only add libc.so if $(build-shared) is yes.

	* math/Makefile (install-lib): New variable, list libieee.a.
	(non-lib.a): Likewise.
	(extra-objs): Likewise, and ieee-math.o.
	($(objpfx)libieee.a): New target, link to ieee-math.o.
	* math/ieee-math.c: New file.
	* sysdeps/unix/sysv/linux/Makefile [$(subdir)=math]: Remove setfpucw
	and libieee.a stuff.
	* sysdeps/unix/sysv/linux/ieee-fpucw.c: File removed.
	* sysdeps/unix/sysv/linux/i386/ieee_fpu.c: File removed.
