Patch to add lang.generated-manpages Makefile hook

["Joseph S. Myers" <jsm28 at cam dot ac dot uk>]

This patch makes language subdirectories use a lang.generated-manpages
target, a better way of ensuring they're only built when the tools are
available than each directory checking $(GENERATED_MANPAGES) itself.

At present only Fortran has a non-dummy <lang>.generated-manpages
target, but I hope that a new version of the patch to generate Java
manpages <URL:http://gcc.gnu.org/ml/gcc-patches/2001-07/msg00442.html>
will be sent that applies to the mainline using this mechanism and
follows the current practice of the other generated manpages for using
the GFDL and handling Invariant Sections.

Bootstrapped with no regressions on i686-pc-linux-gnu.  OK to commit?
