Most recipe-sysroot dependencies are handled by these prefuncs. "configure" is special with a decidated task, prepare_recipe_sysroot which runs beforehand. do_prepare_recipe_sysroot does not have to be run before/after fetch/unpack/patch, they're independent tasks. If fetch/unpack/patch have sysroot dependencies and those tasks rerun, stale items from the sysroot could be uninstalled and since prepare_recipe_sysroot doesn't re-run, they could be missing by the time configure runs. Fix this by adding the prefunc for do_configure which would ensure the sysroot is in a good state. This issue can be reproduced by modifying do_unpack and watching binutils-native and vulkan-headers failing due to missing makeinfo or ninja.

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.
