Using ar/link wrapper to check inclusion correctness.

[chen3feng]

Currently, blade use a <target-name>.incchk file to pass infomation to the inclusion check script, it generates a <target-name>.incchk.result file if the check is OK. The ar link command depends on the result file.

Consider writing wrapper scripts of ar/link to merge the 2 processes.

Benefit:

• Simpler dependency
• Lesser output (hide the check command description echo)
• Performance increasing by reduce ninja scheduling?
