perf tools: Add feature check for libbabeltrace

Browse Source 
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

  Auto-detecting system features:
  ...                         dwarf: [ on  ]
  ...                         glibc: [ on  ]
  ...                          gtk2: [ on  ]
  ...                      libaudit: [ on  ]
  ...                        libbfd: [ on  ]
  ...                        libelf: [ on  ]
  ...                       libnuma: [ on  ]
  ...                       libperl: [ on  ]
  ...                     libpython: [ on  ]
  ...                      libslang: [ on  ]
  ...                     libunwind: [ on  ]
  ...                 libbabeltrace: [ on  ]
  ...            libdw-dwarf-unwind: [ on  ]
  ...                          zlib: [ on  ]
  ...     DWARF post unwind library: libunwind

NOTE The installation of the [1] to to used by above make:
     $ git clone git://git.efficios.com/babeltrace.git
     $ cd babeltrace
     $ vim README
     $ ./bootstrap
     $ ./configure --prefix=/opt/libbabeltrace
     $ make prefix=/opt/libbabeltrace
     $ sudo make install prefix=/opt/libbabeltrace

Please make sure that the /opt/libbabeltrace/lib directory is in your
LD_LIBRARY_PATH:

 $ export LD_LIBRARY_PATH=/opt/libbabeltrace/lib
