* and add -fmacro-prefix-map as well

* the default STAGING_DIR_NATIVE starts with STAGING_DIR_HOST and the
  only difference is '-native' suffix at the end

* this can lead into replacing STAGING_DIR_NATIVE path with just -native
  if STAGING_DIR_HOST is listed in DEBUG_PREFIX_MAP before STAGING_DIR_NATIVE

* I've noticed this by accident in python3-matplotlib where buildpaths
  QA warning was triggered only for lib32-python3-matplotlib and it was
  because pybind11 path to STAGING_DIR_NATIVE was mapped to only
  '-native/<path>' in python3-matplotlib build (which doesn't trigger
  buildpaths QA and lib32-python3-matplotlib the macro path wasn't
  replaced at all, because of 'lib32-' prefix in:
  
-fdebug-prefix-map=/OE/build/oe-core/tmp-glibc/work/i586-oemllib32-linux/lib32-python3-matplotlib/3.7.2/lib32-recipe-sysroot=
 \
  
-fmacro-prefix-map=/OE/build/oe-core/tmp-glibc/work/i586-oemllib32-linux/lib32-python3-matplotlib/3.7.2/lib32-recipe-sysroot=
 \
  
-fdebug-prefix-map=/OE/build/oe-core/tmp-glibc/work/i586-oemllib32-linux/lib32-python3-matplotlib/3.7.2/recipe-sysroot-native=
 \

Sending as RFC, because I haven't build whole world with this
and there might be better way to do this or more buildpaths
issues triggered by this than fixed
