So it appears that adding the pre-processor macro broke the build and I was compiling an empty libdhrl.a. Removing the macro allowed the libdhrl.a to populate. I was thinking about it, and the libdhrl.yml file specifies that RTEMS_SMP is required to enable and build, so a pre-processer macro shouldn't be needed?
