Right, I was going to point this out, the policy has been to not even
try to build features that will likely fail due to not being widely
available in distros.
So please do as with libbabeltrace, where it is only built if one
explicitely asks it to be, see:
commit 6ab2b762befd192b90704c5c7898f5abf8ebb387

perf build: Disable libbabeltrace check by default
Disabling libbabeltrace check by default and replacing the
NO_LIBBABELTRACE make variable with LIBBABELTRACE.
Users wanting the libbabeltrace feature need to build via:
$ make LIBBABELTRACE=1
The reason for this is that the libababeltrace interface we use (version
1.3) hasn't been packaged/released yet, thus the failing feature check
only slows down build and confuses other (non CTF) developers.
