[Cbc] muti-thread compile for cbc-2.7.8

[Ted Ralphs]

I just built Cbc 2.7.8 in OSX 10.8 with --enable-cbc-parallel and executed
with "-threads 4" and it works fine. You'll have to give some more details,
such as what compiler(s) you're using. I'm using the g++ that comes with
XCode.

i686-apple-darwin11-llvm-g++-4.2 (GCC) 4.2.1 (Based on Apple Inc. build
5658) (LLVM build 2336.11.00)
