                     19:        framework.  Users must update and reinstall usr.sbin/config
                     20:        before building a new kernel.

                     25:        linker is installed into /libexec, and all programs in /bin

                     28:        you have the libraries and shared linker in the new locations,
                     29:        with:

                     37:            -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
                     38:                root ofan external toolchain (e.g. /usr/local/gnu).  This
                     39:                enables the cross-build framework even for TOOLCHAIN_MISSING
