This patch improves strcat performance by using strlen and strcpy. Strlen has a fast C
implementation, so this improves performance even on targets which don't have an optimized strlen and strcpy - it is 25% faster in bench-strcat. On targets which don't provide an optimized strcat but which do have an optimized strlen and strcpy, performance gain is > 2x.
