scripts: Add script for creating binary archive

This patch adds scripts/create-binary-archive.sh which helps
us create a common tarball containing headers, static library
and firmware ELFs for all platforms.

This script can be used for release purpose OR for compile
testing all platforms.

Example usage commands are as follows:

1) Binary release archive for 32bit systems
./scripts/create-binary-archive.sh -s "bin" -x 32 -d

2) Binary release archive for 64bit systems
./scripts/create-binary-archive.sh -s "bin" -d

3) Compile test for 32bit systems
./scripts/create-binary-archive.sh -x 32 -t

4) Compile test for 64bit systems
./scripts/create-binary-archive.sh -t
