objcopy: Support cross-build for stripping symbols

Currently, the 'objcopy' does only support native-build since
the commit number 4efef62f0ead16b4f8ca2c6ccf0a77ce112f73b9
Let's add cross-build as well as native-build to strip symbols.

v3:
- support if statement for arm64

v2:
- Replace 'EQUAL' with 'DEFINED' for handling Other Linux distributions
  as well as Ubuntu 14.04 and for handling in case of native-build.

v2:
- support cross-build to strip debug symbols of native arm binaries
