That's not how Yum works. It would move the unresolvable dependency to
that mysterious package and report its name instead, because it would
pull in the libmudflap-devel upgrade into the transaction set.

Mind you, that's the most common form of a broken dependency: the
attempt at upgrading a package that is still needed by stuff in the
local RPM database.
