[uClibc] buildroot, toolchain or root_fs?

I've only been working with uClibc for a short time but this is what 
I've gotten to work.

If you're targeting an embedded system, you might want 'toolchain'. I'm 
targeting embedded ARM Linux with a 'toolchain' build via an x86 RedHat 
Fedora Core-1 machine (gcc-3.3.2).  I changed 
toolchain/gcc-3.3.x/Makefile, setting ARCH to arm and typed 'make'.

I built 'buildroot' first by misunderstanding. 'buildroot' builds a 
complete uClibc runnable system. I wound up with compiler and tools 
that would run on ARM-linux targeting ARM-linux instead of running on 
x86-Linux targeting ARM-linux. Oops.
