Wow.  These latest changes are really causing a problem.  Actually the 
only file I changed was glibc, but is caused 214 unexpected errors in gcc 
and required a sed in sysklogd.

It's getting late and we'll need to investigate.  I'll look at it tomorrow.

All the gcc failures look like:

FAIL: c-c++-common/asan/asan-interface-1.c   -O0  execution test

with different gcc switches.  The most common is in the files like
c-c++-common/asan/bitfield-?.c  where the ? is 1, 2, 3, 4, 5
c-c++-common/asan/clone-test-1.c
c-c++-common/asan/global-overflow-1.c
c-c++-common/asan/halt_on_error-1.c
c-c++-common/asan/heap-overflow-1.c
c-c++-common/asan/memcmp-1.c
c-c++-common/asan/misalign-1.c
c-c++-common/asan/null-deref-1.c
