gcc12 on macOS

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I hope there are people here interested in gcc12 on macOS - it started
failing in jperkin's macOS bulk builds, because homebrew removed a
patch we were using:

https://reports.pkgci.org/Darwin/12.3/arm64/20250718.1323/gcc12-12.5.0/checksum.log

The package is at 12.5.0 now anyway, so can someone please update it
to use the 12.5.0 patch (if any)?

Thanks,
 Thomas
