LAYERDEPENDS is a string of this format: "DEPEND1 (optional version) DEPEND2 (optional version) ..." However when we parse LAYERDEPENDS in _get_layer_collections() we parse it as a simple string, and if any optional versions are there the 'depends' field is wrong. For example, running yocto-check-layer might result in such errors: ERROR: Layer meta-python depends on (>= and isn't found. ERROR: Layer meta-python depends on 12) and isn't found. Let's use bb.utils.explode_dep_versions2() to parse LAYERDEPENDS, and create a string that contains all dependencies, effectively skipping/ignoring any optional versions.

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.
