  If only user mode is supported, that should be documented in the help text.

  This can be removed.

  We normally put spaces before and after =

  This looks very much like a $(host-autotools-package).  Even if the
configure is not a proper autoconf script and barfs on all the unknown
options that buildroot adds, you can still override the CONFIGURE_CMDS.
But I expect that just setting HOST_QEMU_CONF_OPT will be enough.
