perf build: Disable libbabeltrace check by default

2015-03-30T13:24:27Z

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.
