Alex Crichton 89f8bc2561 Fix parallel makefile builds
All the copying of files amongst one another was apparently causing something to
get corrupted. Instead of having files fly around, just update the directories
to link to.

# $(1) is the stage

# Every recipe in TARGET_STAGE_N outputs to $$(TLIB$(1)_T_$(2)_H_$(3),
# a directory that can be cleaned out during the middle of a run of
# the get-snapshot.py script. Therefore, every recipe needs to have
# an order-only dependency either on $(SNAPSHOT_RUSTC_POST_CLEANUP) or
# on $$(TSREQ$(1)_T_$(2)_H_$(3)), to ensure that no products will be
# put into the target area until after the get-snapshot.py script has
# had its chance to clean it out; otherwise the other products will be
# inadvertantly included in the clean out.
