--- Comment #12 from joseph at codesourcery dot com <joseph at codesourcery dot com> 2011-06-12 12:48:53 UTC --- The reason for the error is that no spec matches the option. For most targets, the option is matched in LINK_PIE_SPEC (only), which is part of LINK_COMMAND_SPEC; Darwin uses its own LINK_COMMAND_SPEC (as does DJGPP). I would advise making Darwin behave similarly to other targets by including an appropriate spec for this option in Darwin's LINK_COMMAND_SPEC.
