[IsabelParedes]

This fixes

- LinkError: imported function 'env.xerbla_' signature mismatch

when loading libRblas.so because

// r-base/src/main/print.c

#ifdef FC_LEN_T
NORET void F77_NAME(xerbla)(const char *srname, int *info,
			    const FC_LEN_T srname_len)
#else
NORET void F77_NAME(xerbla)(const char *srname, int *info)
#endif
