Separate user and internals manuals.

	* Makefile.in (info, $(docdir)/gcc.info, dvi, gcc.dvi): Update
	dependencies.
	($(docdir)/gccint.info, gccint.dvi): New targets.
	(maintainer-clean, install-info, uninstall): Update.
	* doc/.cvsignore: Add gccint.info*.

 In most cases, you need @file{libgcc.a} even when you want to avoid
 other standard libraries.  In other words, when you specify @option{-nostdlib}
 or @option{-nodefaultlibs} you should usually specify @option{-lgcc} as well.
 This ensures that you have no unresolved references to internal GCC
 library subroutines.  (For example, @samp{__main}, used to ensure C++
