So I tried checkout out before Ingo's changes to libbabeltrace detection, i.e.:

[acme@zoo linux]$ git checkout -b ttmp 9a75606ca06d94aab1ed0dbe96935e3f89dfb81c

And it works:

[acme@zoo linux]$ git checkout ttmp
Switched to branch 'ttmp'
[acme@zoo linux]$ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ; time make LIBBABELTRACE_DIR=/opt/libbabeltrace/ -C tools/perf O=/tmp/build/perf install-bin
make: Entering directory `/home/git/linux/tools/perf'
  BUILD:   Doing 'make -j4' parallel build

...                          gtk2: [ on  ]

...     DWARF post unwind library: libunwind

  MKDIR    /tmp/build/perf/util/

But if I checkout tip/perf/core:

[acme@zoo linux]$ git checkout -b ttmp2 tip/perf/core
Branch ttmp2 set up to track remote branch perf/core from tip.
Switched to a new branch 'ttmp2'
[acme@zoo linux]$ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ; time make LIBBABELTRACE_DIR=/opt/libbabeltrace/ -C tools/perf O=/tmp/build/perf install-bin
make: Entering directory `/home/git/linux/tools/perf'
  BUILD:   Doing 'make -j4' parallel build
config/Makefile:709: No libbabeltrace found, disables 'perf data' CTF format support, please install libbabeltrace-dev[el]/libbabeltrace-ctf-dev

It doesn't work, bisecting:

[acme@zoo linux]$ git bisect bad
b49f1a4be701c2386ccc7496dc8442cf26424d5c is the first bad commit
