makefiles

Patch to put hsc2hs output into a parallel hierarchy in build/hsc/ instead of alongside their source files. Was it an improvement? Hard to say... some things get more complicated, but I've noticed I gradually move more and more toward separating generated output and source. That's good, right? Is this a progression that every program goes through as it gets larger, gradually accumulating more makefile cruft until it finally culminates in the Custom Build System? Is there a way to sidestep all this?

But anyway, it's an opportunity to pull out the GNU make doc and write more complicated make rules, which is always, you know, a pleasure.
