Python uses AC_RUN_IFELSE to determine the byte order for floats and doubles, and falls back onto "I don't know" if it can't run code. This results in crippled floating point numbers in Python, and the regression tests fail. Instead of running code, take a macro from autoconf-archive which compiles C with a special double in which has an ASCII representation, and then greps the binary to identify the format. This is essentially a backport of the Python 3 patch in oe-core 1781b87.

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.
