Adding feature check for babeltrace library [1], which will be used for
perf data file CTF [2] conversion in following patches.
The babeltrace library is now automatically detected as standard
feature. It's possible to specify LIBBABELTRACE_DIR make variable to
specify location of installed libbabeltrace, like:
$ make LIBBABELTRACE_DIR=/opt/libbabeltrace/
BUILD: Doing 'make -j4' parallel build

... gtk2: [ on ]
... libaudit: [ on ]
... libbfd: [ on ]
... libelf: [ on ]
... libnuma: [ on ]
