mk/host-bottom: Introduce HOST_CONFIG_STYLE

This is helpful when a package could use HOST_STYLE=auto but doesn't
ship a conforming configure script. In that case, one can now set

| HOST_STYLE=auto
| HOST_CONFIG_STYLE=manual

and define a custom host-configure target while still making use of the
auto targets for anything else.
