This is not a good idea. I mean -DXTRADB_OK=1. XTRADB_OK is set
internally if HAVE_IB_GCC_ATOMIC_BUILTINS or HAVE_IB_SOLARIS_ATOMICS or
MSVC is defined. Depending on what exactly is defined, different parts
of the code are enabled. When you force XTRADB_OK=1 without enabling any
of the other defines, XtraDB will not enable any of these parts of the
code. Most probably it won't compile at all.
Instead of forcing -DXTRADB_OK=1, you need to do -DHAVE_IB_GCC_ATOMIC_BUILTINS=1.
Then XtraDB will compile as if gcc atomic builtins were available.
They probably are anyway, but cross-compilation caused the test to fail.

If you intend to use tokudb, then you probably should not ignore it.
if you don't intend to use tokudb, you can as well specify -DWITHOUT_TOKUDB=1
and it won't be compiled at all.

That's exactly what I meant above. This error happens because you've
