I was thinking that sources.mak was used by Android build engine only.
 Would it be good to have a sources.android.mak file?

The problem is that whatever prefix we add to LOCAL_SRC_FILES forces
it to be also used when declaring the build target like this


$(intermediates)/$(SRCDIR)/some_file: some_deps

IMO, adding the logic for the addprefix needed for auto-tools might be
easier, than adding a for cycle to remove the $(SRCDIR) for Android
needs.  The relative directory is used only by autotools.
