Currently, kselftests does not have a generalised mechanism to skip compilation and run tests when required kernel configuration flags are missing.
This patch introduces a check to validate the presence of required config flags specified in the selftest config files. In case scripts/config or the current kernel config is not found, this check is skipped.
In order to skip checking for config options required to compile the test, set the environment variable SKIP_CHECKS=1.
example usage: ``` make SKIP_CHECKS=1 -C livepatch/ ```
