[OE-core] [PATCH 1/4] bitbake.conf: update DEBUG_PREFIX_MAP with -fmacro-prefix-map

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

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'.
