configure: Allow host fragments to react to --enable-host-shared.
This makes the host_shared value available to host makefile
fragments.
It uses this to adjust Darwin's mdynamic-no-pic in the case that
shared host resources are required.

* mh-darwin: Require a non-shared host configuration to
enable mdynamic-no-pic where that is supported.
