Limits the number of OpenMP threads to match BB_NUMBER_THREADS. This prevents OpenMP (libgomp in particular) from falling back to using all the available CPUs, which behaves poorly when attempting to limit build usage, especially when attempting to build in a container.

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.
