I have done pretty much nothing at all yet, and I won't be able to do
anything today.  I just checked what has happened in my local copies
of aclocal.m4 and configure.in, and the only thing that I did not
check in was the following patch that does not achieve its purpose
well, since the prefix might need to strip bin/architecture IIRC (at
least for TeXlive and/or teTeX this is likely).

I think it would be better to create another aclocal.m4 macro that
does this job in a more general way, something like
AUCTEX_PATH_PREFIX(prefix1, prefix2, executable)
which then sets the prefix1 and prefix2 variables to the path-relative
stuff in the manner I outlined previously.
