Instead of using SHLD_PLUGIN for modules, we should keep
SHLD_MODULE, but use a new SHLD_LIBRARY for shared libraries.

It would also be nice to use

AC_LIBREPLACE_SHLD
AC_LIBREPLACE_SHLD_FLAGS

and

AC_LIBREPLACE_MDLD
AC_LIBREPLACE_MDLD_FLAGS

from libreplace. There we could also add the sun specifc flags genericly
for source3 and source4.
