Do these tests include all the various cases of whether someone has (a
sufficiently recent version of) makeinfo installed and whether they have
info files present in srcdir?

I.e.,

* No (or too old) makeinfo installed, info files present in srcdir: info 
files get installed.

* No (or too old) makeinfo installed, no info files present in srcdir: 
install just quietly doesn't install info files.

* Current makeinfo installed (whether or not info files present in
srcdir): info files get built (at least if necessary) and installed.

All of these were tested to work when Texinfo was removed from GCC CVS
<http://gcc.gnu.org/ml/gcc-patches/2000-12/msg00457.html>; I haven't been
systematically testing them since then, but nontrivial changes to info
file installation do at least have the potential to break some cases while
leaving others working.
