automatically compute some dependencies on s-gtype

[Rafael Espíndola <rafael dot espindola at gmail dot com>]

The attached patch adds code to gcc/Makefile.in that automatically
computes some dependencies on s-gtype.  It uses GTFILES_LANG_DIR_NAMES
and GTFILES_FILES_FILES to create a list of gtype-*.h and gt-*.h files
and adds a rule that makes them dependent on s-gtype.

This removes the need for makefile rules in the front end and is less
error prone since config-lang.in and Make-lang.in can't get out of
sinc again.
