These patches add support for the Cortex-A8 processor used in the
Beagleboard among others.

Indentation seems wrong, otherwise it's fine. From what gcc version is
cortex A8 supported? We should probably make it depend on that minimal
version as the build otherwise breaks?

We already have 4.4.2 support in BR.

Gcc 4.4.1 added support for armv7-a, but there was a bug for c++
exceptions that made libstdc++ non-PIC which was fixed in 4.4.2. So
4.4.2 and later would probably be a good bet.

Just a FYI - yesterday learned, the hard way (I.E: before reading the release notes):
There was an ABI change from gcc-4.3 to gcc-4.4 for MIPS/MIPSel
There are a lot of things affected, I gave up on that and switched back to 4.3.whatever

Yes, there's still some issues with 4.4.x, that's why we still default
to 4.3.4.
