Description: We have seen the library dependency issue when we are
linking the libomp.lib or libiomp5md.lib while building the library
for static multithreaded scenario. So we are removing the linking of
openmp library for static multithreaded blis library build. So that
user can link any openmp library(libomp.lib or libiomp5md.lib) while
building their applications by linking static multithreaded blis library.
