Hello Brendan,

that is a bug that has been in libbsd for about one day. For some background see

   https://lists.rtems.org/pipermail/devel/2019-March/025379.html

That problem should be fixed by that commit:

   https://git.rtems.org/rtems-libbsd/commit/?id=9fabaaec3e5100f0dd130bbf8af2705d39cc5ac7

So please just update and try to rebuild.

Best regards

Christian
