I provided dummy functions for the libitm weak refs in the first
version of this.
(a) this is unnecessary (except in the corner-case of testing lto)
because there is never a need to use the crts unless libitm is linked.
(b) it no longer works across all *x86*-darwin* because weak linkage
behavior differs.
the solution is to require the library to be present (no problem,
since the crts are only fired up for -fgnu-tm) and to remove the dummy
funcs from the crts,
OK for trunk?
