OK. This flips the priority, but we're assuming that the Makefile
doesn't allow you to actually set both flags (at least not easily). And
I think that is the case, even after your loosening of the error for
"auto" in the previous patch, because the whole DC_SHA1_SUBMODULE
code-path is in the "else" block for DC_SHA1_EXTERNAL. Good.
