This is how I'm doing cross-compiles here:

# glibc
#export ARCH=i386
# uclibc
export ARCH=i386
export CROSS_COMPILE=i486-linux-uclibc-
# uclibc64
#export ARCH=x86_64
#export CROSS_COMPILE=x86_64-pc-linux-gnu-
# arm eabi
#export ARCH=arm
#export CROSS_COMPILE=arm-linux-uclibceabi-

test x"$CROSS_COMPILE" = x || cross="CROSS_COMPILE=$CROSS_COMPILE"

make $cross "$@"

By uncommenting relevant part on top, I can do different cross-builds.

I olny ever tried cross-compiles with GNU toolchain, built from sources
locally.
If you want to do the same, but having difficulty building
tollchain, I can help.
