Strangely, I still fail to build.
I'm trying on u-boot/master 6d1966e12 (dated Aug 1st 2014)
Building with the following commands, on clean build directory:
export BUILD_DIR=/home/lab/dev/u-boot/out/all_mips
export USE_PRIVATE_LIBGCC=yes
export CROSS_COMPILE=mips-linux-
./MAKEALL -a mips
Here is what I get with the toolchain from kernel.org:
