Tell OpenBLAS to use locking, by passing USE_LOCKING=1.
Locking is implicitly enabled when USE_THREAD=1.
However, if USE_THREAD=0 (i.e. OpenBLAS itself will run in
single-threaded mode) but an application makes OpenBLAS
function calls from multiple threads, then locking is
mandatory for correct operation.
