Silence some make rules
The make rules for generating the file micro-revision.i and changing the permissions of the test scripts are IMO not configured correctly.
The micro-revision generation rule runs on every call to make. Its function requires it to stay up-to-date to the current state of the repository. My question is whether the act of updating/generating the file needs to be communicated back to the user every time? IMO it clutters the terminal (especially on make check where the focus should be on the test results not on output of irrelevant make rules).
Changing the permissions of the test scripts should be silent IMO unless silent rules are disabled. It clutters up the terminal when running make check.
