Add option '-fmacro-prefix-map' to DEBUG_PREFIX_MAP. It could resolve buildpaths qa warnings which caused by macros '__FILE__' and '__BASE_FILE__'. Though option '-ffile-prefix-map' could cover '-fdebug-prefix-map' and '-fdebug-prefix-map' both, it is not supported by 'as' and causes buildpaths qa warnings of glibc: | QA Issue: File | /work/i586-poky-linux/glibc/2.29-r0/packages-split/glibc-dev/usr/lib/crti.o | in package contained reference to tmpdir So only add '-fmacro-prefix-map' to DEBUG_PREFIX_MAP rather than replace '-fdebug-prefix-map' with '-ffile-prefix-map'.

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.
