-ffile-prefix-map is supposed to be a superset of -fmacro-prefix-map

-ffile-prefix-map is used.
While the user can specify -fdebug-prefix-map when building assembly
files via gcc, it's more ergonomic to also support -ffile-prefix-map;
especially since for .S files that could contain the __FILE__ macro,
one would then also have to specify -fmacro-prefix-map.

OK. Sorry for the long delay.
