Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

    Please find enclosed a patch which enables me to build the bare-bsp for
    sh-rtems.

    Changes:
        1. Add preinstall to libbsp/bare/include/Makefile.in
        2. Removed FORCEIT, add preinstall to
        libbsp/sh/gensh1/include/Makefile.in
        3. Disabled support of set_vector from sh code (shared/setvec.c is still
        present but isn't used anymore), set_vector replaced with standard rtems
        functions.

    Problems still present:
        1. Support of spin-delays in bare bsp
        2. Proper support of cpu frequency

    To configure I used:
        <srcdir>/configure \
        --target=sh-rtems \
        --prefix=<instdir>/sh-bare \
        --enable-bare-cpu-model=sh7032 \
        --enable-bare-cpu-cflags='-Wall -m1 -DMHZ=20
        -DCPU_CONSOLE_DEVNAME="\"/dev/null\""'
        --enable-rtemsbsp=bare \
        --disable-networking \
        --disable-cxx \
        --disable-posix \
        --disable-tests

    IMO, if there are no objections to this patch, a similar approach should
    be applied to all CPUs/BSPs (esp. hppa1.1, mips64orion, ppc403, because
    they apply set_vector inside of libcpu).
