ok. I see. We have neon instructions enabled by default in xilinx toolchain.
I have sent the patch which create and add
PLATFORM_RELFLAGS += -mfpu=neon
to config.mk.

This should solve the problem with compilation.
No problem to add this patch as the first in this serial not to break bisectability
of the tree.

Thanks,
Michal
