Unfortunately, even though the patch follows existing practice in
other front-ends, they're all wrong.

This change would cause `make info' to not attempt to generate info
files for the front-ends, like it does for cpp, gcc and gccint, even
if using an old version of makeinfo.

It seems to me that the correct patch would instead remove the
dependency on the info files from the front-end install-info rules,
and then, to avoid problems with make -j install, replace those
dependencies with doc, such that, if info files are to be generated,
doc depends on info depends on lang.info depends on <frontend>.info
depends on the front-end info files.

If you'd rather have more accurate dependencies for make -j install,
to avoid stalling the install of info files, you may want to try
instead having the <frontend>.install-info depend on
<frontend>.$(BUILD_INFO), defining a phony <frontend>. target for the
case of an empty BUILD_INFO.
