	* Makefile.in: Re-write build procedure mainly to honour
	dependencies correctly but also allow making in the build
	directory by configuring the relevant variables.  The lib[FIU]77
	subdirs do dependency checking of their objects.  Stamp files
	dictate when to run (new) archive targets in subdirs.  Some
	tidying of variables.  Supply full set of standard targets.
	* configure.in: Move much of testing to new configures in
	subdirs.  Tidy up handling of RANLIB etc.
	* stamp-h.in, libF77/configure.in, libI77/configure.in,
	libF77/configure, libI77/configure: New files.
	* libF77/Makefile.in, libI77/Makefile.in, libU77/Makefile.in:
	Change in step with libf2c/Makefile.in.
