Add a PACKAGECONFIG for profile-guided-optimisation, and default to whether qemu-usermode is available. Move --enable-optimizations to the pgo optimisation as all this currently does is use the PGO rules, causing a performance hit if PGO isn't actually used.

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.
