Using the glob function to map signatures to sstate files is very slow when the sstate is large and accessed over nfs. The lookup now only loads the necessary prefixes and doesn't use glob as all. Unfortunately I don't have access to the systems where the performance isse was noticed and on my test system the glob is fast enough that the performance numbers aren't useful. I could verify that file list returned by the new code is the same.

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.
