forgot to add, all these builds are with
a patch to unwind-ia64.h. For example, for 4.8
branch, the patch is (credit to gerald@freebsd.org):

On FreeBSD 10.0-CURRENT #5 r252055,
with ports tree at r322480, I can built
lang/gcc, which is now 4.6:

This is with Gerald's patch:

I think it was fixed due to recent binutil fixes.

Since 4.7, 4.8, 4.9 all build fine on this platform,
I'm no longer interested in 4.6.4.
I'm therefore closing this PR.
