Subject: [PATCH] Fix use of mod_ssl as a DSO linked against static SSL
 libraries; also stop linking all of support/* against the SSL libraries:

* acinclude.m4 (APACHE_MODULE): Define MOD_FOO_LDADD which each
module .la library will be linked against.
(APACHE_MODPATH_ADD): Link static modules against the provided libraries.
(APACHE_CHECK_SSL_TOOLKIT): Put SSL libraries in SSL_LIBS and export
that to config_vars.mk.

* support/Makefile.in: Link ab against SSL_LIBS.

* modules/ssl/config.m4: Add SSL_LIBS and distcache libraries to
MOD_SSL_LDADD.
