Right. Some linkers seem to do reordering themselves, while others
require the ordering to be specified in the proper dependency order; I
prefer a linker that doesn't do any reordering itself --- it can lead to
surprises and doesn't handle well cases where the same symbol is defined
in multiple libraries.
