RFR: CODETOOLS-7903228: RerunTest2 fails with an alternate build directory

Fri Jul 1 22:11:15 UTC 2022

Please review a test fix for another test that fails when run with an alternate location for the build directory.

The fix is as before, ensure to use absolute paths after using `cd` within a make rule.

With this fix in place, there should be  no more test failures when running with an alternate build directory.
