target-i386: Introduce feat2prop() for CPU properties
This helper replaces '_' with '-' in a uniform way. As a side effect, even custom mappings must use '-' now. Signed-off-by: Igor Mammedov <imammedo@redhat.com> [AF: Split off; operate on NUL-terminated string rather than '=' delimiter] Signed-off-by: Andreas Färber <afaerber@suse.de>
