I posted my patch:

http://gcc.gnu.org/ml/gcc-patches/2012-11/msg01530.html

Since it didn't fix anything at the time,  there was no incentive
for anyone to review it.  Please someone review my patch
and get over with it.

FWIW,  libjava has the same issue with libstdc++ dependency
as a bootstrap library.  I applied the same solution to libsanitizer.
