[GSoC 2020: Daily Update]: Building EPICS with RTEMS5

Wading in late but I thought I saw something that was contradictory:

Build BSP with --enable-networking
Code needs rtems-libbsd

If the code needs rtems-libbsd, then you MUST build fill with
--disable-networking.

If EPICS code needs rtems-libbsd, that limits the number of BSPs that can
be used but you need to always use libbsd.
