autoconf has not been released in a number of years. However many changes have been made to the gnu-config config.guess/.sub since 2.69, including new architectures, OS variants, etc. In order to enable these targets without creating patches for the source itself populate the gnu-config files from the sysroot as is done with autotools recipes. Whilst it is not possible for the autoconf recipe to bootstrap its configure task (using the autotools_do_configure), the files can be manually copied into the target location.

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.
