 > however the muniversal portgroup also currently requires a standard
 destroot phase, which the tbb port does not have

 The port could easily use a standard destroot phase that does nothing, the
 problem was I didn't think there was a way to do something else after that
 but before the muniversal portgroup does the merging, but it turns out
 there is: one can define a `merger-post-destroot` proc.

 An additional problem was that the arch needs to supplied to the test
 phase. The muniversal portgroup didn't have the capability to specify
 different args or env vars in the test phase, so I added that in r138613.

 The attached patch implements a working universal variant, as far as I can
 tell, though I haven't tried to use tbb after this change (don't know
 how). May I commit it?
