Feedback welcome.
Zack's original proposal.

I renamed the first option to "--print-install-dir" since
it seems to be exactly that.

After doing this, I noticed that
the output for the latter two lines in --print-search-dirs
have leading "=" sign, which seems a little odd, but
I leave it as it is.
Comment on the choice of
the option names are welcome.
Execution example.

PS:
After saying all this, I would rather see the following code
if (print_search_dirs)
{
printf (_("install: %s%s\n"), standard_exec_prefix, machine_suffix);
printf (_("programs: %s\n"), build_search_list (&exec_prefixes, "", 0));
printf (_("libraries: %s\n"), build_search_list (&startfile_prefixes, "", 0));
return (0);
}
turned into
if (print_search_dirs)
{
printf ("install: %s%s\n", standard_exec_prefix, machine_suffix);
printf ("programs: %s\n", build_search_list (&exec_prefixes, "", 0));
printf ("libraries: %s\n", build_search_list (&startfile_prefixes, "", 0));
return (0);
}
(note the no translation)
since the output for this option is more likely
to be fed into other programs and not read by humans.
(And what is the cost of understanding English tag 'install',
"programs", and "libraries" anyway for the intended audience.)
[If the above change is acceptable, this whole patch I am posting
is not necessary.]
Patch is below.
