[omniORB] Crosscompiling

[Robert Schwebel]

Hi, 

Crosscompiling omniORB currently does not work:

So the makefiles try to run cross-compiled binaries on the build
machine, which is wrong. Automake would use CC_FOR_BUILD & friends for
that kind of problem, but I've no idea at the moment how to fix that
with the current makefiles. 

Does anyone with more intimate knowledge of the omniorb makefiles have
an idea how to fix this?
