gcc 11: use gcc12 instead

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

Hi!

I found a program that wants gcc 11, but that is not packaged (and
thus '11' is not supported in GCC_REQD). So I thought that we could
just depend on gcc12 when 11 is requested, and have the correct
version in GCC_REQD.

Does anyone see a problem with the attached diff?
 Thomas
