Are they really matter? Or I can shut these errors up.

Looks like I haven't supplied you with the compiler for test_kc705_hifi, for
which these errors are reported. I've built it and put it here:

  http://jcmvbkbc.spb.ru/~jcmvbkbc/tmp/201604261801/x86_64-gcc-5.3.0-nolibc-xtensa-test_kc705_hifi-elf.tar.xz

Please integrate it into your system along with other xtensa compilers.

Thanks.
