[U-Boot] [PATCH] Make arm926ejs use -mabi=apcs-gnu to avoid EABI problems

[Simon Kagstrom]

Using -mabi=apcs-gnu allows Marvell Kirkwood-based boards to boot with
the EABI changes introduced in commit
f772acf8a584067033eff1e231fcd1fb3a00d3d9.

Wolfgang can live with this change to make Kirkwood builds work again:

It would be nice though if owners of other arm926ejs-boards could test
the patch and see that it doesn't break things. Depending on the
compiler, you might want to build with USE_PRIVATE_LIBGCC=yes.

I've tested on a OpenRD-base board.
