#4395: Intel 11.1 defines _GNU_SOURCE, breaking the get_nprocs test in thread.cpp

In a bug related to #2053, there's code in
`libs/thread/src/pthread/thread.cpp` that attempts to only call
`get_nprocs` on gnu platforms that define _GNU_SOURCE (cf.
http://lists.boost.org/Archives/boost/2010/05/166414.php)
Unfortunately, intel 11.1 appears to define _GNU_SOURCE, but not provide
get_nprocs:
