libgcc12 build fails on Ventura with Xcode 14.2 due to new undeclared gawk dependency

[nocturne-mit]

I'm migrating to Ventura on an Apple Silicon mac.

After following the standard MacPorts migration doc, libgcc12 fails to build. At the time, there is no gawk available on the system, but the gcc12 Makefile appears to think it should use it anyway, resulting in a gawk invocation failing to create tmp-optionlist, and the build fails.

If I "port clean libgcc12" and then "port install gawk", the libgcc build succeeds.

:info:build checking for gawk... gawk

and later:
