Great, thanks!  I bootstrapped and ran the asan testsuite.  I'm now seeing
lots of FAILs due to:

  ASan runtime does not come first in initial library list; you should either
  link runtime to your application or manually preload it with LD_PRELOAD.

...which Paolo mentioned in the other thread that he is hitting this too.
There was some discussion on what to do, but has there been a decision on
how to fix this yet?  Or is it fixed upstream and we just need to merge
that fix too?
