Fix boot hang caused by incompatible libgcc which has been observed when using later Linaro toolchains like gcc-linaro-arm-linux-gnueabihf-2012.09-20120921_linux or gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.
That's no surprise, since U-Boot links libgcc into itself. And since PXA2xx is armv5-compatible, you'd need armv5 toolchain. The hang you're observing is most likely happening in some aeabi_* function pulled in from libgcc, which contains some armv7 instruction(s), which in turn upsets the xscale.
I would suggest that we drop this patch, but I would also suggest that we do the same thing kernel does and just enable CONFIG_USE_PRIVATE_LIBGCC globally for everyone to break this constant nonsensical influx of toolchain-related problems. This nonsense has been dragging on for too long. Tom? Albert?
