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.

     4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-4.1-alpha-mieee-default.patch
     5 Set the default behavior on alpha to use -mieee since the large majority of
     6 time we want this (bad/weird things can happen with packages built without
     7 -mieee).
     8 
     9 To satisfy those people who may not want -mieee forced on them all the time,
    10 we also provide -mno-ieee.
