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.

    10       Add support for the Signal Processing Engine.  This will set up
    11       the toolchain so that it supports the SPE ABI extensions. This
    12       mainly targets Freescale e500 processors.
    13 
    14       Setting this option will append "spe" to the end of your target
    15       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    16       configure/build system will know to include SPE ABI support.
    17       It will also automatically add "-mabi=spe -mspe" to your
    18       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
    19       so you do not need to explicitly add them.
