crossgcc: patch out uses of $(P) variable from gcc/ada build

Gentoo likes to use that variable for itself and insists on keeping it.
Meanwhile it doesn't seem to be set or used anywhere else in the gcc
build, and it seems there was a big $(P)-pruning going on in 2000,
so why is it even (still) there?
