indeed: this is the clean solution.  Besides, moving them from
ada/Makefile.in to ada/Make-lang.in would have created two different
dvi resp. doc targets with commands of their own in the generated
gcc/Makefile, which would only work with double-colon rules.

During bootstrap, I had another problem with those targets: they depend on
xgnatug, which dumped core on me when built during the bootstrap with the
bootstrap GNAT (3.13p on sparc-sun-solaris2.5.1 in this case).
