If it's taking that long, I suspect you're also building a toolchain
and kernel everytime.  When I realized that partial rebuilds weren't
practical, I switched to using an external toolchain.  With an
external toolchain and an external download directory, doing a
from-scratch basic rootfs build takes about 6-7 minutes on a single
CPU, 2GHz AMD Athlon64.

I also switched to building my kernel outside of buildroot.  If you're
doing any sort of kernel development (or just want to try
experimenting with kernel configurations), doing the kernel builds
with buildroot is pretty clumsy.

Once you've got a kernel configuration figured out and set in stone,
it could be useful to have the kernel built by buildroot, but it
doesn't seem to be a paractical way to do kernel development.
