Ok Egor,

  I changed the patch somewhat.  I added code so the option is documented
in the help for configure.  I also moved the flag setting into configure.host
where other such flag setting is performed.  In the future, other platforms
may use the flag as well.

  The patch is checked in.  The ChangeLog follows.
