Wouldn't this break using -iprefix for a prefix that is not a directory, ie:

	gcc -iprefix /foo/bar/bletch- dummy.c

would find include files in:

	/foo/bar/bletch-include

Given the -B option already works this way (where it is a true prefix and
not a directory), I don't see a reason for -iprefix to be different.
