It's autoconf magic. It's enough that the AC_SUBST is seen at all,
even though it isn't executed.

Try the attached patch. It's safer than restoring the original values
of LIBCURL since the idea of allowing a user to pass in LIBCURL is to
try and find the library or add special link stuff. If that fails,
then best to clear the variable altogether rather than try and link to
something that already failed.
