[mythtv] compile issues - latest macOS SDK (11.3) / Xcode (11.5)

[John Hoyt]

I'm trying to build new app bundles for master and fixes/31 using my
standard compile script, but am now getting errors in the compile process
with the latest Xcode release.

The error occurs on both master and fixes/31 for both intel and arm
platforms.

Everything is still working on older versions of macOS (i.e. Catalina /
High Sierra)

Here's the compiler error:

Configuring libmythsoundtouch...

Any suggestions on how to troubleshoot this?  If I add a ';' to
mythtv/mythtv/VERSION the "error: expected ';' after top level declarator"
errors go away.

Thanks for the help!
