Building lttng-modules for a "lib32" multilib, then changing to a "lib64" multilib with "lib32" removed doesn't rebuild lttng-modules. This is due to the multilib pieces in RPROVIDES being added after RecipeParsed which is after the signatures are generated. Changing this to RecipeTaskPreProcess allows the multilib components to be accounted for correctly in the task hashes. This addresses failures on the autobuilder seen in lib64-core-image-sato-sdk builds where lttng-modules was being reused from qemux86 world build's lib32 version.

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.
