Subject: configure: Allow host fragments to react to --enable-host-shared.
X-Git-Tag: upstream/2.42~1942
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c841db953822200b5f9babeb7ddeaefe0bb377df;p=platform%2Fupstream%2Fbinutils.git

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.
