Details: - Relocated the _MSC_VER-guarded cpp macro re-definition of strerror_r (in terms of strerror_s) from bli_thread.h to bli_env.c. It was likely left behind in bli_thread.h in a previous commit, when code that now resides in bli_env.c was moved from bli_thread.c. (I couldn't find any other instance of strerror_r being used in BLIS, so I moved the #define directly to bli_env.c rather than place it in bli_env.h.) The code that uses strerror_r is currently disabled, though, so this commit should have no affect on BLIS.
