backend-rdp: enable undefined functions errors.

b_lundef was overriden for the RDP backend since it triggered linking
errors due to functions that were defined in a missing dependency. This
issue was fixed, so the override is removed. The global project's
linker parameters are now applied to the RDP backend.
