I probably should point out that I don't think this is the case anymore.

GCC apparently detects what capabilities the currently selected binutils
have so when the first native compiler has been compiled using the
cross, it will emit code that can't be assembled using the system
binutils (because it uses features from the new binutils that aren't
supported by the older system ones). In other words, you can't rebuild the
native compiler using the system binutils.

If the worst comes to the worst, I can create a dependency on the
devel/cross-binutils port.
