[Qemu-devel] [PATCH] configure: re-add current options in config-host.mak

["Michael S. Tsirkin" <mst@redhat.com>]

commit bdf523e6923f1e667055e947e71fc600549cefae
    "configure: Add config.status to recreate the current configuration"
moved current configure flags to config.status

This makes sense, but this makes it harder to bisect problems that
trigger with a specific set of flags only, since old configure is not
smart enough to find them there.

Simply add the options as a comment in the format
old configure expected - they are then ignored by the new configure.
