In addition to toggling libsnappy support, this allows a qemu-native build to explicitly disable snappy support. When building qemu-native, the configure script will detect libsnappy on the build machine and improperly enable snappy support. This can corrupt the sstate cache if the cache is populated with a qemu-native build with snappy improperly enabled, and the cached qemu-native gets used on another build machine that does not have libsnappy.

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.
