There is a test and it fails, of course:
⬢[acme@toolbox perf]$ cat /tmp/build/perf/feature/test-libopencsd.make.output
test-libopencsd.c:9:2: error: #error "OpenCSD >= 1.1.1 is required"
9 | #error "OpenCSD >= 1.1.1 is required"
| ^~~~~
⬢[acme@toolbox perf]$
But the fact that I ask for CORESIGHT=1 should have the build fail then,
i.e. if one explicitely asks for a feature and it can't be built, fail
the whole build.
