asterisk/Makefile.rules
Kevin P. Fleming 0f01ace7af Ensure that linker version scripts (used for symbol export control) always exist.
Using wildcard matching in the Makefile is not adequate to determine whether
an export file should exist for a module or not, so instead we'll just
create one if the module needs one, or copy the default one if it does not.
