I personally also don't think that running benchmarks under make check is
good idea....
In future it should take quite large about of time...
Embedded environments should be problem for benchmarking. I am not very
experienced in this topic but I believe tests should easily get out of
memory or stack space.
Note that I've added bzip into benchmarks, but it generates random file
in memory and then compress it to memory, so it don't do any IO. Measures
just the sorting loops..

I've picked hanoi just because I've played a bit with scheduling of prologues
of functions at i386 so I needed some test that depends heavily at function
calls...
Once I will have enought tests, I will probably remove these that are not
usefull.

When I run tests more times, there is usually not higher differences that 1%,
wich should be OK IMO.
