It was added by cgd in May 1995 and evidently only enabled in the
alpha port because that's probably all Chris needed it for.
I added the doshutdownhooks() call to arch/i386/i386/machdep.c in
August 1995, so it's my fault that it's called incorrectly there. (It
works fine under normal circumstances, but I should have compared it
to the alpha code more carefully and/or paid more attention.)
