This fixes a problem on some platforms where a pre-inst guile
incorrectly picks up an old installed library (e.g. from
/usr/local/lib) instead of the not-yet-installed newly built library.

* pre-inst-guile-env.in (subdirs_with_ltlibs): Add libguile.
* pre-inst-guile.in (subdirs_with_ltlibs): Add libguile.
(dyld_prefix): Construct and export dyld_prefix in a similar way
to ltdl_prefix, to allow pre-install dynamic linking to work on
MacOS. Thanks to Roger Mc Murtrie for reporting this problem.
