Is there any reason why sup would refuse to update some files?

I am missing pretty well everything in sys/lib/libkern/arch/*/*.S

I just FTPed the i386 files, so my kernel built.  This was the first time
I tried to build a -current kernel since 1.3 was released.

My "last.ksrc-i386" file has entries for the contents of libkern, yet sup
didn't get the files.

How could this have happened?

Here's my supfile:
