Not so 'odious,' of you realize that:
	(1) one can't build 'kernel libraries' in a
		machine-independent place without special
		support for pulling in machine-specific options
		(e.g. things dealing with global pointers, FP
		regs, etc.), and,
	(2) having the libraries compile with different flags _per
		kernel_ is a useful feature.

i looked at the libc path lines, and i'm not at all sure why they
should be there, at all.
