Review Comment:
Was due to cmake does work by specifying ``CMAKE_TOOLCHAIN_FILE`` which
translate to x86 compiler with option ```--target=....```. Where as
```configure``` require cross compiler to be specified or explicitly add
```--target``` option.
Anyway I could handle it with top level cmake invocation to pass cross
compiler instead of tool chain.
