CMake, in it's infinite wisdom, when searching for libraries (using
find_library) will look inside the libraries PREFIX/lib, PREFIX/lib32, and
PREFIX/lib64. In a multilib SDK more than one of these will exist (potentially
all three) and obviously for a given build configuration only one of those is
valid. This search path is hard-coded deep inside CMake but by setting
CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX we can bypass it and set an explicit
lib<SUFFIX> to use.
Do this by writing ${baselib} into the environment file, and then stripping
"lib" from this to obtain the suffix in the cmake-specific environment script,
which is then read in the CMake toolchain.

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.
