Thanks for the great work! I can't include it yet, because of the
open issue.

The important part of the Openscenegraph build is this one:
-- Performing Test _OPENTHREADS_ATOMIC_USE_GCC_BUILTINS
CMake Error: TRY_RUN() invoked in cross-compiling mode, please set the
following cache variables appropriatly:
_OPENTHREADS_ATOMIC_USE_GCC_BUILTINS_EXITCODE (advanced)
I don't really know how to set cache variables, but I guess it's just
some file of definitions which we'd have to initialize, i.e.
echo '_OPENTHREADS_ATOMIC_USE_GCC_BUILTINS ...' > '$(1)/somefile'
However, I find it very strange that this error message doesn't occur
with GCC 4.4.
Greets,
Volker
