This is a bit strange: bitmaps.h is included in menus_helpers.h, which is included in menubar_modedit.cpp.
It works fine for me (and not only for me). And if include bitmaps.h is missing, this is not the linker which have an issue, but the C compiler.
May I ask you to see what exactly happens on your kicad source tree. At least try to rebuild Kicad after a full cleanup.
