many warnings, but at least it builds now.

native/make: add missing target
tests: fix test_hwtimer_spin

Actually test hwtimer_spin, not hwtimer_arch*

`hwtimer_wait` calls `hwtimer_spin` only for delays `<= 6`, that's why a
pure test_hwtimer_spin test should not pass values `>6`.
Also decrement delay in steps of 1.
tests: add test_hwtimer_wait

It contains the old test functionality of test_hwtimer_spin.

Add "compile everything" tool

Having many tests is quite futile if they aren't executed once in a
while<sup>[citation needed]</sup>.

Alas, this is not the purpose of this PR. This PR adds the tool
"compile_test.py", which executes `make buildtest` for all applications
in `examples` and `tests`, and prints a comprehensive list of the
results.
