Newer kernels (4.14/v4.15+) have dependencies for the build of modules (and hence external modules). Without these dependencies explicitly in the build chain, you can end up with build failures like: work-shared/qemux86/kernel-source/scripts/extract-cert.c:21:25: fatal error: openssl/bio.h: No such file or directory | #include <openssl/bio.h> | ^ | compilation terminated. | make[2]: *** [scripts/extract-cert] Error 1 | make[1]: *** [scripts] Error 2 To ensure that these headers are in place, and that the scripts use our build environment flags, we add a dependency on openssl-native and use oe_make to invoke the build. Older kernels have no issues with the extra dependency, so there's no need to make this conditional.
