This is rather recapitulating the previous discussions. The
problem with extra ad-hoc top level command line arguments
is that they don't fit in with the structure we're trying
to impose on new QEMU options, which is that they should
have a particular syntax and sit inside option groups
(in this case, -semihosting-config).
