And just after that, it appears that if custom-cflags is not set, then it strips all the -O* flags (if i'm reading the code correctly), which would explain why there's no -O set for the compiler..... # Strip optimization so it does not end up in compile string filter-flags '-O*' # Strip over-aggressive CFLAGS use custom-cflags || strip-flags
