So far it seems to be working fine.  I haven't figured out what
the minimal set of required files is.  Initially I took a
snapshot of everything under output/staging.  Subsequent makes
using that as an external toolchain failed because it found
files in output/staging/usr/share that it didn't expect to be
there.  I removed usr/share from my "toolchain", and now builds
seem to work fine.

For now I think I'll stick with a buildroot-generated toolchain.
