	I'm doing something similar now (though in a much less elegant
	fashion - thanks for the make fragment :). It seems to make
	more sense for the Makefile for a package to know about
	this - such as having
	in the relevant package makefiles. It allows people to add
	-ffast-math and the few packages with issues to automatically
	exclude the flags, without having everyone who wants to set
	-ffast-math have to work out which packages to exclude.
