Merge branch 'ps/clar-build-improvement'

Fix for clar unit tests to support CMake build.

* ps/clar-build-improvement:
  Makefile: let clar header targets depend on their scripts
  cmake: use verbatim arguments when invoking clar commands
  cmake: use SH_EXE to execute clar scripts
  t/unit-tests: convert "clar-generate.awk" into a shell script
