Comment(by illogic-al@…):

 Without c++ support this port is useless for  us. If ppc64 fails then i
 can just change the line back to "i386 ppc". It's a compiler so it should
 be able to compile for at least those two archs.
 I might as well just submit it under a different name then in the interest
 of time.
