If you've built a toolchain with crosstool, ensure the generated tools 
are in your PATH and then simply run them as you would normally:

  arm-softfloat-linux-gnu-gcc -o test test.c

etc.

Your machine name may differ depending on what you built with crosstool 
but arm-softfloat-linux-gnu is what I'm using for balloon2.

The above will let you build executables that will run under Linux, 
though you'll need to make sure the shared libraries being used by 
crosstool match those on the balloon (or I suppose you could 
add -static).

The crosstool toolchain is also sufficient for compiling a replacement 
kernel (export ARCH="arm" CROSS_COMPILE="arm-softfloat-linux-gnu-").

Bye for now,
