[meta-intel] [PATCH] mkl-dnn: do not use host machine instructions

[Naveen Saini]

For GNU* Compiler Collection version 5 and newer
the default options are `-march=native -mtune=native`,
which should not happen in cross compilation environment.

ARCH_OPT_FLAGS=\"\" does not allow to use host machine
instructions.

For more information, please check:
