[PATCH] bitbake.conf: reset default value of DEBUG_PREFIX_MAP

[<kai.kang@windriver.com>]

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

Reset default value of DEBUG_PREFIX_MAP with '-fdebug-prefix-map'.
Specifying -fdebug-prefix-map is equivalent to specifying all the
individual -f*-prefix-map options which means including
-fmacro-prefix-map and -fdebug-prefix-map currently. Option
-fmacro-prefix-map helps to avoid buildpaths qa warnings which caused
by __FILE__ macro expansion for packages such as llvm and librepo.
