Triggered by looking at why Python doesn't find db.h (because it greps db.h for a regex, and db.h is actually a oe_multilib_header wrapper) I realised that the only reason we have to oe_multilib_header db.h is because one typedef is different between 32-bit and 64-bit architectures. However, the typedef is for a 64-bit integer so instead of using long (64-bit) or long long (32-bit), just use int64_t. Some of the overly complicated configure tests need to be deleted after this change but that is safe as we're building in a controlled environment and can assume int64_t exists. With this done the header doesn't change between architectures, and it doesn't need to be wrapped by oe_multilib_header.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
