[boost] How to establish boost configurations for cross-compilers not currently covered?

The boost config manual
(http://www.boost.org/doc/libs/1_55_0/libs/config/doc/html/index.html)
does not explicitly address the case where one is attempting to
determine the relative lack of C++98 compliance of a cross-compiler
(e.g., for an embedded system) that is not already within Boost's
supported set of compilers.

Is there a clear process documented somewhere for how to go about
this?  If not, I would appreciate any tips.  I have more than one
cross-compiler that I am interesting in "Boost"ing.

Thanks,
Dave
