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
