when compile use ：make BINARY=64 NO_CBLAS=1 NO_LAPACK=1 SANITY_CHECK=1 USE_THREAD=0
it will break as follows：
parameter.c: In function 'blas_set_parameter':
parameter.c:687: error: 'blas_num_threads' undeclared (first use in this function)
parameter.c:687: error: (Each undeclared identifier is reported only once
parameter.c:687: error: for each function it appears in.)
