I noticed that using bitbake-layers add-layer followed by a devtool command resulted in bitbake re-parsing all of the recipes, which is annoying. Upon closer inspection I could see that devtool was moving the workspace layer path to the end of BBLAYERS if it happened to be somewhere in the middle - there's no need for it to be doing this. This occurred because we were passing the current workspace path to remove and the "new" path to add even if the path is not being changed, and I think earlier versions of bb.utils.edit_bblayers_conf() didn't move the existing entry under these circumstances as it clearly does now. Fix it so we only pass the path to be removed if we're actually changing the path.

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.
