Agree, but i thought that this may be a bit more intrusive than touching the
one invalid invocation.

Providing an empty info: and perhaps also html: would be the cleanest thing.
>From the looks, html: may also be needed since gcc/Makefile.in reads:
TEXI2HTML = $(MAKEINFO) --html

OTOH, html is apparently not in the default install target, so if somebody
requests it explicitely, it may be ok to fail noisily.
