Fix Makefile race conditions

* configure.ac: Make cross/* and related directories.
* cross/Makefile.in (src/verbose.mk, lib/libgnu.a)
(src/config.h): Stop making directories here.
(lib-src/config.h): New config.h rule.
($(LIBSRC_BINARIES)): Add it.
(clean): Don't remove CLEAN_SUBDIRS, but clean inside.
