i'm not sure i like this.  the build environment is expected to
provide a valid compiler, and the above assumes how the compiler
works.

if we really want to support this without user-env setup, then
i think a confiure test (from tools/compat) would be better than
forcing this option here directly.

(also note this is not the first time this sort of issue has
arrived, and we always asked the build-env provider to fix it,
but i'm not against eg, the configure test idea.)

thanks.
