RTEMS 6 has moved the legacy network support out of the main repo to a 3rd party library. This change adds support for using the legacy networking stack with EPICS in a backwards compatible way. A BSP can be built with libbsd or the legacy stack and by default EPICS 7 assumes libbsd. This patch also fixes the LDFLAGS adding the RTEMS LDFLAGS imported from Makefile.inc.
