If the problem is only with executable-find, we could provide a
solution for that one alone.  Starting with the simplest one: if the
specific environment knows in which directory to look for the
browsers, it could simply prepend the directory, making the browser
file name an absolute one.  Or use locate-file, which accepts path as
an argument.  Or something.

Tweaking exec-path will have a much more dramatic and wide effect, so
we should try to avoid that, IMO.
