[RFC] Make "all" depend on "info"

[RFC] Make "all" depend on "info"

[Tom Tromey]

I've broken "make info" a couple of times now, because I sometimes
forget to run "make info" after modifying a Texinfo file.

I don't know why gdb's "make all" doesn't build the info pages.  I
suspect this was some Cygnus-local oddity back in the day.

This patch changes doc/Makefile.in so that the info pages are built by
"make all".  As a point of reference, Automake has essentially always
worked this way.  According to the Automake manual (I didn't
double-check) this is required by the GNU coding standards.

IIRC, another weird consequence of the current situation is that if you 
do ./configure && make && sudo make install, the doc artifacts will be 
generated during make install, so owned by root.  I believe everything 
should be generated by "make", and make install should only install the 
files in the prefix.

I'm in favor of this change.

I think it makes sense, especially because "info" the default
documentation format for GNU.

I was wondering if it would also make sense to build the documentation
on the BuildBot.

I haven't checked this in yet, because I remembered there are a number
of bugs in bugzilla from users who don't have (and maybe also don't
want) makeinfo installed.  So, I thought I'd hold off on this until I
find the time to come up with a solution for them.
