ubuntu 16.x LTS

arm-rtems5-gcc 7.4.1

all tools and rtems were remote/master pulls from the git repos.

by building for a different bsp (xilinx_zynq_a9) first, I then built
the realview board and it succeeded...thus telling me that the
realview setup is missing a required component in the build, that it
was only able to find AFTER creating for the xilinx board.
