Fixed build breakage from 37e946683f1bb6a.

In 37e946683f1bb6a I fixed a build failure from a warning, which are
treated as errors.

Newer versions of GCC have a feature (documented here:
http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html) where unknown
warning flags are ignored.

In older version of GCC (such as 4.1 or 4.2), it appears that these flags
aren't ignored, resulting in an error.

Check for automake 1.14 in bootstrap.
