[Gc] GC 6.8 & PowerPC

Finally getting a chance to look at this ...

I think the issue is just that you didn't specify --host correctly.  It should presumable be a GNU platform string that also gives the OS, like powerpc-860-linux-gnu.  Hence the configure script is not recognizing that you're on a Linux platform.
