The patch breaks the compiler on i386.
For a "boost" file I just got

movl $_ZN5boost12test_toolbox18output_test_streamD1Ev@GOT(%ecx), %ecx

with the patch installed.
It might be possible to separate the i386 and amd64 cases better
in the patch, but since there are other intendependencies are
mentioned in the gcc list, the whole thing is rather dangerous.
For pkgsrc/mozilla, it might make sense to use gcc34.
