It's left-over from a side-effect of an abandoned attempt of
mine to fix severe bugs in the vtable-gc support in binutils
(don't use it).  The vtable-gc stuff was obsoleted (hence the
patch abandoned) by the v3 (aka. "new") c++ abi which
unfortunately makes vtable-gc much harder to implement.
(I hope those who don't agree prove me wrong, though unlikely.)

Fair enough.  FWIW, the need was to cause allocation failure
pass on NULL to the caller instead of calling abort.
