Well, this *only* happens if you do a build from the git repository;
for this situation I still think that you should have all the tools.

It's somehow bizarre to implement a `--with-doc=...' configuration
option that makes it possible to explicitly disable the compilation of
the examples, and at the same time to complain that
`--with-doc=examples' doesn't work because some tools are missing – we
are still talking about compiling from git!

It's OK with me to mention this trick somewhere in a README, but
`touch gnu.eps' essentially means crippling the documentation, making
it incomplete.  For this reason I vote `no'.
