Oh sorry, I misread the code. Anyway, I don't think that this code is
good, because if I want to get one of jdk tool, I expect that I will get
it from '-compilejdk' if this option's specified, and from '-jdk',
otherwise. But w/ Christian's patch I will get tool from '-jdk' if tool
exists there, that may confuse.

I fully agree w/ you and I'm really sorry about the situation.
But I don't see big difference between 'hotspot-runtime-dev' and
'hotspot-compiler-dev', so *this* change "really have to be reviewed
more broadly as they affect everyone".
