Kurt, this is a newer diff then the one I sent you off list.

I took a look at this failing on sparc64 and i386. On sparc64 it
fails because there's a native component to this port and upstream
does not have sparc64 support. On i386 building kotlin fails due
to out of memory and increasing the java heap more is not possible
on i386. So mark this port amd64 and aarch64 only.

Also noticed SUBST_VARS M_ARCH is not used in pkg/* and appears
to be carried along from games/lwjgl which uses it.

None of these changes change the existing packages so no package
bump.

okay?
