The contents of the expand_cache is meant to match the return value of getVarFlag() but the implementation was mostly in expandWithRefs(). If an incorrect key was passed to expandWithRefs(), or a variable was only partially expanded with no remove processing, the cache could become corrupted. Move the code to getVarFlag making the data lifecycle very clear, meaning other calls to expandWithRefs() cannot corrupt the cache. The expand_cache reset code needs to be moved ahead of any remote data connectors too, since the expand_cache is now on the local side of the connection.

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.
