 Most likely you configured buildroot for a subarchitecture that is not
supported by your platform.  You can run the working cross-compiler with
the -v option; in the long list of configure options you'll see something
like '--with-cpu=sparcsfleon'.  That is the subarchitecture you should
use for buildroot too.
