Details: - Disabled error checking in netlib-to-BLIS parameter mapping functions. If the char value input to these functions was not one of the defined values, bli_check_error_code() with the appropriate error code value would be called, resulting in an abort(). This was unnecessary and redundant since these routines are currently only used within the BLAS compatibility layer, and they are only called AFTER parameter checking has already been performed on the original BLAS char values. If the application tried to override xerbla() to prevent an abort() from being called, this error checking would still get in the way. Thus, instead of reporting the error situation to the framework (ie: calling abort()), an arbitrary BLIS parameter value is now chosen and the function returns normally. Thanks to Jeff Hammond for finding and reporting this issue.
