We've seen some reproducibility issues on the autobuilder in perf where the size of the python module varies slightly between systems. After some head scratching and removing the --quiet option to the python module build, you can see it using -Lrecipe-sysroot-native in the linking commandline for the module. This means it is linking against the native library on systems where that works, skipping it and using the target one otherwise, probably with warnings in logs we've not seen. The fix is to inherit the python3targetconfig class which ensures that the target sysroot is used, then the byte differences between the builds go away and things are sane(r) again.

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.
