Sorry for the extra commit... there was an error in the smpdhrl0x.yml files that caused the build to fail when another non-x86_64 BSP was compiling. The DHRL library would properly exclude libdhrl.a from the build, but would fail later when trying to link the tests. Modfied the enabled-by flags in the YML to ensure those are excluded as well. Tested by recompiling for ARM/Zynq and build succeeded without attempting to link non-existent tests.
