building splitted gcc manual (errors in md.texi)

gcc.texi has documented the build of the manual splitted to two
manuals. This patch adds the build targets to build these manuals and
adds an configuration option --with-splitted-gcc-manual to configure.

However running makeinfo for the splitted manuals, produces some
errors in md.texi:

makeinfo  -I../../src/gcc -o portgcc.info portgcc.texi
./portgcc.texi:187: Next reference to nonexistent node `G++ and GCC'.
./portgcc.texi:4213: Cross reference to nonexistent node `Cross Runtime'.

makeinfo: Removing output file `portgcc.info' due to errors; use --force to preserve.

	* configure.in: Add --with-splitted-gcc-manual option.
	* install.texi: Document it.
	* Makefile.in: {use,port}gcc.{texi,info,dvi}: New targets.
	install, uninstall, clean: Adjust.
