[LLVMdev] Usage of /dev/null in makefiles wrong

make: Warning: File `/dev/null' has modification time 4.9e+03 s
in the future
make: Entering directory `/usr/src/llvm/llvm/lib/System'
At the end of the compilation it emits something about clock skew
The time of /dev/null on my box is weird because of udev and/or
time local settings. When it's created, the init scripts didn't
have set the right locale. So in the first few hours after I
turned my box on, it's timestamp is in the future.
But hey, it's odd that /dev/null is a "make" target anyway.
When I change line 1474 in Makefile.rules from
-include /dev/null $(DependFiles
then this strange and weird warning vanishes.
