It uses gcc on build machine during go-cross-canadian bootstrap, but the gcc version may be old and not support option '-fmacro-prefix-map' which is one of default values of DEBUG_PREFIX_MAP. So set default value of DEBUG_PREFIX_MAP for go-cross-canadian.

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.
