I started to look into this, but it seems like I'd need a bit of duplication to handle byte compiling the installed files in two different Makefile targets.

The alternatives are templating, automake style, or GNU make'isms like the $(call) function, or possibly running `$(MAKE) bytecompile` to do all byte-compilation in a shareable submake. Do any of these sound good? Any other thoughts?
