question about overriding the platforms statement in subports

[Sergey Fedorov]

Just in case, dropping gcc-4.2 from this line does not change anything,

https://github.com/macports/macports-ports/blob/0dea602a9f195ca39a6a0318d54c10b80036d35d/lang/gcc14/Portfile#L350
Sorry, cannot check at the moment.

At least before that was a bug in the port, which introduced circular
dependency. I have not checked in a while if it is still relevant or have
been fixed.
