What prompted this? Although it looks correct, I also see the following
unmangled symbols:

0000000000000000 T copy_with_crc
0000000000000000 T crc_finalize
0000000000000000 T crc_reset
0000000000000000 T read_buf
0000000000000000 T _tr_flush_bits
0000000000000000 T x86_check_features

PTAL.

(I've also updated version in README.chromium to a correct one, since presubmit
checks want me to make a change in README.chromium).

Shouldn't google.patch be updated, too?
