rules: new macros ptx/config-version and ptx/config-md5
There are several packages that get the version/md5 from the ptxconfig
variables PTXCONF_<PKG>_VERSION / PTXCONF_<PKG>_MD5. These new new macros
can be used for this and add basic sanity checking:
If the package is enable, then the version and md5 must not be empty.
Otherwise the string 'undefined' is returned to make it obvious that the
version is currently not available.
