as discussed on irc we will disable it for cross builds now,
because we dont have good solution at the moment.. it's
similar case as for fixdep tool:
3a70fcd3a4db tools build: Fix cross compile build
...
We need to add support for host side tools build, meanwhile
disabling fixdep usage for cross arch builds.
I'll make a change to disable this for crossbuild and
work on common solution later
thanks,
jirka
