  yes, but the issue is that "make clean" should still have the same
effect WRT to resetting that symlink, especially since the error
message tells the user to set ARCH and the user (i.e., me) *has* set
ARCH.  put another way, if i do a config with a specific setting for
ARCH, it seems non-intuitive to *not* reset the symlink representing
that architecture.
