Hello all,
I just pulled from the master of both rtems
(362cf319d44e7e64987f12aa36ea030e6298c586) and rtems-libbsd
(d892051f37c2c4ad7f345f6a817ea3d38e56a431) trees and ran into an couple
undefined references when linking an application outside of the tree. The
application doesn't directly use either symbol and has worked unmodified on
older trees. This build issue is not present when using the 5-freebsd-12
branch of rtems-libbsd on the same application code. I can move forward with
the 5-freebsd-12 branch so this isn't a show stopper for me.
