	The Great Bit File Move:
	* configure.in (AC_INIT): Look in include/ for features.h.
	(sysnames): Add include as the final search directory.
	(AC_OUTPUT): Create a bits directory in the build directory.
	* Makeconfig (CPPFLAGS): Look in include/ for libc-symbols.h.
	* Makefile: Make sure the target directory exists when installing
	<gnu/stubs.h> and <gnu/lib-names.h>.
	* csu/Makefile: Use $(compile.S) and $(compile.c) instead of
	invoking $(CC) directly, as the former have the full include path.
