[Cbc] muti-thread compile for cbc-2.7.8

Hi Stefan,

So there is no proximity search algorithm in 2.7.8, why is it that it
does not issued an error when I use the proximity switch (i.e.
-proximity on) in 2.7.8?

Anybody manage to compile CBC trunk that does not segment fault when
using proximity search?
