wxmac needs to build --without-mediactrl on 64-bit hosts (subsumes #33366)

Users of tools that fail when trying to link non-existent frameworks run into problems on 64-bit macs, because the old 32-bit QuickTime framework does not and never will exist as a 64 bit library.

This has been submitted upstream and accepted into wxmac HEAD, however a released version is not yet available and likely won't be for quite some time.

This patch lets us actually get code to compile without waiting 8 months for a release.
Can you inline this function instead? Thanks.
