raspberrypi2 libbsd 5-freebsd-12 does not build

[Chris Johns]

Hi,

An RSB build of libbsd is failing with ...

/opt/work/rtems/5/lib/gcc/arm-rtems5/7.5.0/../../../../arm-rtems5/bin/ld: 
./libbsd.a(rtems-kernel-nexus.c.18.o): in function `nexus_ofw_map_intr':
/opt/work/chris/rtems/rsb/rtems-source-builder.git/rtems/build/rtems-libbsd-v2b9172c9d42d056b6fb16d667091e2ee3ac64009-arm-rtems5-1/rtems-libbsd-2b9172c9d42d056b6fb16d667091e2ee3ac64009/build/arm-rtems5-raspberrypi2-default/../../rtemsbsd/rtems/rtems-kernel-nexus.c:359: 
undefined reference to `bsp_fdt_map_intr'

I have raised a blocker ticket to track this ...
