Fix building with DSO support. If any module is configured to be

compiled for shared support then APR_HAS_DSO is enabled and -ldl is
added to the LIBS variable.  -ldl may need to be modified based on
platform.  If no modules are designated as shared then APR_HAS_DSO is
disabled and nothing is added to LIBS.  In basic testing this compiled
without errors or warnings.
