Add partial implementation of ndk_compat (#54)

* First implementation of ndk_compat
* Restrict building of linux_based_hardware_detection to UNIX
* Fix variable declaration and printf formatting
* Restrict ndk compat to UNIX style systems
* Restrict cpu_mask index to 32
* Fix values display in ndk-compat-test
* Addressing comments
