[Cbc] muti-thread compile for cbc-2.7.8

[xiwen]

Hi Stefan,
I have tried downloaded different verions and the 2.4.2 seems working:

wangx at qrprdbal803:~> cbc -threads 8
Coin Cbc and Clp Solver version 2.4.2, build Nov 28 2012
command line - cbc -threads 8 (default strategy 1)
threads was changed from 0 to 8
Total time 0.00
wangx at qrprdbal803:~>

Does this means the cbc parallel is correct?

Thanks
Xiwen
