Per my previous comments, if you don't have a linker installed which provides 
usable dynamic lookup of weak
symbols, the gcc47 package won't pass those testsuite test cases (which also 
arise in real code). Except for
the odd exception of a user who is locked into a specific Xcode release because 
of a 3rd-party compiler (which
is bound to be a rare situation), I don't see the point of regressing the 
performance of the FSF gcc compiler
by allowing users to link with a broken linker.
