[boost] Serialization Jamfile.v2 and SPIRIT_ROOT

Hi Robert,

I have seen that you have changed the
libs/serialization/build/Jamfile.v2

Some comments on this:

1) The issue not only applies to borland, and not only to
    serialization.

2) I am running the regressions with a modification to
    user-config.jam. I.e.:

    using borland : : : <cxxflags>-Ipath_to_spirit ;

    This works well, and if the path is not set the compiler
    will spill out a message, that will inform the user, that
    another version of spirit is needed.

3) Your change will insist on a SPIRIT_ROOT beeing available,
    despite the fact that the include already might have been
    specified correctly for the toolset.

4) Will your change also work with path-constant, set in
    site-config.jam ? Policy is to get away with environment
    variables.

Thank you,
Roland
