Subject: [PATCH] configure.in: Put {start,end}-sanitize-for-fsf around code
 that removes some programs based on host or target; this silent failure to
 configure isn't appropriate for the separate one-tool releases FSF puts out.

.Sanitize: Remove that code if "for-fsf" is on command line; remove just the
markers if it isn't.
