Patch to sourcebuild.texi

["Joseph S. Myers" <jsm at polyomino dot org dot uk>]

More places where front ends may require changes to core GCC were
missing from the documentation (as shown by the now fixed bugs of
--enable-shared=ada and --with-gmp not being documented).  Fixed thus.
It passes "make info" and "make dvi".  Applied to mainline and 3.4
branch.

Still not listed are the make distclean line in gcc/Makefile.in

	-rmdir ada cp f java objc fixinc intl po testsuite 2>/dev/null

(which I'd favour removing, it doesn't serve a useful purpose) and the
list in install.texi of which directories use which auto* versions
(should be temporary until all use the current versions).  Also, the
QMTest targets for G++ are still in a subideal place (gcc/Makefile.in
rather than gcc/cp/Make-lang.in,
cf. <http://gcc.gnu.org/ml/gcc-patches/2003-06/msg00438.html>) and
nothing is documented about how front ends should support QMTest.

	* doc/sourcebuild.texi (Front End): Add details of more
	installation documentation required.
