    2.6.14 with RT21 fails to build for ppc (ibm440gx).

          CC kernel/timer.o
        /home/egan/downloads/linux-2.6.14/kernel/timer.c: In function `phase_advance':
        /home/egan/downloads/linux-2.6.14/kernel/timer.c:991: error: `time_phase' undeclared (first use in this function)

        make[1]: *** [kernel] Error 2

    Adding config GENERIC_TIME to arch/ppc/Kconfig results in a failure later in
    the build.

    After some research it looks like this breakage was introduced by rt16.
    rt15 builds OK.
