PR35401 and PR30572 are gcc 4.3.0 release blockers on darwin

[Jack Howarth]

   Current gcc 4.3 branch incorrectly links all of its
shared libraries against the system libgcc instead of
the copy it builds and installs (PR35401). It appears
that the fix applied for PR30572 may have been
disturbed since it is no longer working.
   Shouldn't PR35401 be escalated to a release blocker
for gcc 4.3.0?
