Subject: Fix baremetal arm_compute_validation build errors

* Add -C flag to instruct preprocessor not to strip comments. This is to
prevent marker comments like '// fall through' that suppresses certain
warnings from being removed.

* Fix unused variable warnings.

* Add M_PI definition that's missing from certain toolchain standard
libraries.

Resolves COMPMID-4054
