This turns out to be convenient in cases where one's build system
defaults to "ld --fatal-warning" but occasionally one would like to
override it. It's also parallel to existing gcc conventions for setting
and unsetting options. See attached diff to ld/lexsup.c; it's against
2.17 but patches OK against 2.18.
