Using the RPM %{release} field in baselibs.conf

Hello.
Is it in any way possible to use the ${release} field in baselibs.conf? Using <release> doesn’t work, unfortunately. I could alter the base package provides not to emit a “<name>-<version>-<release>” provide, but I’d rather just set a full, correct dependency in the 32 bit package.

Any ideas? Thanks in advance.
