I think have the general idea.

I guess I don't add $(LDFLAGS) because I didn't need it (yet).
If we're building something with "ld -r" or similar, it would be
part of the special cases in $(MK_SHARED_LIB).

If it's too inconvenient, I'll rewrite it.  (I don't know offhand why
it should need the math library, since the ordinary floating-point
stuff is adequate for sscanf's conversions - but it's something to
keep in mind).
