The specific config I tested had the GUI support disabled, i.e just
QtCore, not QtGui.

Though I agree with you that generally speaking, usage on SPARC is
unlikely. But by narrowing the dependency to just script and/or webkit,
we have to propagate it to a lot less packages, which actually means
that supporting this weird SPARC architecture creates less noise, which
is what we want.
