So, you can do it exactly as suggested in the mail you cite.

Well, if you absolutely have to, then put the
    : ${host_alias="mips-elf"}

line in configure.ac right after AC_INIT.  That will relieve your
cow-orkers from creating a config.site file, but of course also make
your package building for mips-elf rather than native by default.

I do suggest you get acquainted with 'info Autoconf "Site Defaults"'
however and reconsider this decision.

The others here are not needed, as they should get set accordingly by
the configure code.

Hope that helps.

Cheers,
