Bugzilla Bug 128587

I type: emerge gngeo
I get: cc1: error: invalid option `tune=i686'
I tried: Deleting the unpacked folder in /var/tmp/portage and remerging it.
I do not have any tune/mtune option set in my make.conf file.  Finally, I
checked the Makefile for gngeo and found nothing about tune/mtune in there.

You just need to switch to GCC 3.4

Well, we should force that dep if it's needed.  Fixed in CVS.   Thanks for the
bug report.
