Hi Karl,

You are right, but the main reasons for this patch were:

- Use same output as ie. target/SDK (cleanup)
- Toolchain build is disabled by default (as is SDK)
- Eventually switch to multithreaded version for XZ  (like your patch [1])



I've done some benchmarks on a machine here (i7 4770K):


tar bz2:    0m19.271s    (now)
tar cfJ:      1m3.384s
xz:            1m19.958s    (patch)
xz - T 0:    0m38.587s    (Future with -T 0 ?)
