gcc: add patch to fix EABI for armv4t

As pointed out by Martin GUY, gcc incorrectly generates armv5t
instrcutions for EABI, even for cores that are an armv4t.
The new patch (for the 4.3 series) fixes the problem by downgrading
the default CPU for EABI to being an armv4t core.

 You have to bar gcc trying to build unwinding at stage 1. Try the
