GDB 7.5 broken without makeinfo

[Paul Smith]

I've seen various bugs reporting that older GDB's were not buildable on
systems which don't contain makeinfo; for example:

http://sourceware.org/bugzilla/show_bug.cgi?id=13638
http://sourceware.org/bugzilla/show_bug.cgi?id=13861

However, I've just tried GDB 7.5 and it's still not buildable on these
systems.  The problem is that the gdb.info output file depends on a
constructed file GDBvn.texi which sets some variables, but this file is
not provided in the distribution file.

As a result it is always rebuilt and as a result of that, gdb.info is
always out of date and always needs to be rebuilt.

I've filed http://sourceware.org/bugzilla/show_bug.cgi?id=14678

It would be handy if someone had a VM or Debian schroot or something to
perform test builds in, where none of the autotools were installed.
This is especially important when changing the makefiles.

Cheers!
