Emerge did this, when confcache was installed and FEATURES=confcache was 
set. But I guess this only works well with once cache file per package, 
not with a global cache that is being used during all emerges.
The configure script tests for lots of features, each test has a name. But 
there is no global naming scheme, so tests for different features can have 
the same name in different packages. I think this is why it did not work 
so well.
