This is not "bug" i believe since i was able to find similar problems in
other projects and they are solved by additional checking -
for apple command line just does not have this parameter. Also i don't have
problem for compilation for host system. It means
that it is taken into account, but it's missed for cross-compilation.

That's why i believe it's bug.
