I don't remember saying that Linux packagers should use the
--layout=system option. For that matter, I prefer if everyone uses the
versioned layout as it produces non-colliding names.

Do you mean is --layout documented?

   --layout=<layout> Determines whether to choose library names
                           and header locations such that multiple
                           versions of Boost or multiple compilers can
                           be used on the same system.

                               versioned (default) - Names of boost
                               binaries include the Boost version
                               number and the name and version of the
                               compiler. Boost headers are installed
                               in a subdirectory of <HDRDIR> whose
                               name contains the Boost version

                               system - Binaries names do not include
                               the Boost version number or the name
                               and version number of the compiler.
                               Boost headers are installed directly
                               into <HDRDIR>. This option is
                               intended for system integrators who
                               are building distribution packages.

And no, --layout=system will not remove the -mt tag. Also for
--layout=versioned, unversioned links are created which remove the Boost
version number tag, but not the compiler tag.
