Normally it doesn't work that way...

...though this time it does:

Notes:

(1) This is a hack; the original code was probably written against an older 
version of unittest and is abusing the framework to some extent. The dummy 
tests I introduced are ugly but should do no harm. 

(2) I tried this on linux only and thus changed 'yasm.exe' to 'yasm' 
unconditionally.
