We should have a hook that is executed for each arch's destroot prior to merging them in the muniversal PortGroup.

This would give us a good place to fix conflicts such as this one in mpich:

We just need to strip the arch specific CFLAGS out of the pkgconfig file, but we have no good place to do that.

I agree that this would be useful. I recall doing something (ugly) in the clamav portfile for a similar issue, so there may be a way to work around it for now (I believe I copied the code from another port at the time).

I fixed this specific need by making the merge code smarter about .pc files, but there are still other cases where this would be useful.

Yes a pre-merge hook might be helpful, however I don't think it's needed in this instance; you can do the fix at post-build time like many other ports already do. See wiki:PortfileRecipes#archflags.
