Trying to test this I get:
[acme@jouet linux]$ make O=/tmp/build/perf LIBBABELTRACE=1 -C tools/perf install-bin 2>&1 | grep babel
config/Makefile:663: No libbabeltrace found, disables 'perf data' CTF format support, please install libbabeltrace-dev[el]/libbabeltrace-ctf-dev
[acme@jouet linux]$ rpm -q libbabeltrace-devel
libbabeltrace-devel-1.2.4-2.fc23.x86_64
[acme@jouet linux]$
Guess we better improve this message... Anyway, trying to find libbabeltrace's
git tree to see if with its master branch this works...
