double64_init: Check psf->sf.channels against upper bound This prevents division by zero later in the code. While the trivial case to catch this (i.e. sf.channels < 1) has already been covered, a crafted file may report a number of channels that is so high (i.e. > INT_MAX/sizeof(double)) that it "somehow" gets miscalculated to zero (if this makes sense) in the determination of the blockwidth. Since we only support a limited number of channels anyway, make sure to check here as well.

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.
