This can make "$ bitbake-layers show-recipes" save about 60% time (14min -> 6min) in my build (more than 3000 recipes) The command "bitbake-layers show-recipes" calls bb.utils.get_file_layer() with each recipe, and get_file_layer() compare the file with each item in BBFILES which makes it very time consuming when there are a lot of recipes and items in BBFILES. So use BBFILES_PRIORITIZED and exit when file is matched, it doesn't make sense to go on the loop when file is matched. And use fnmatchcase to replace of fnmatch since the comparison should be case-sensitive.

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.
