It's a tool that doesn't do what it says on the tin.  What it says is:

# make distclean
#      Delete all files from the current directory that are created by
#      configuring or building the program.  If you have unpacked the
#      source and built the program without creating any other files,
#      'make distclean' should leave only the files that were in the
#      distribution.

What it doesn't say is "Delete all files ..... or building the program,
which were created from an Emacs distribution."

Well, first I'll follow Eli's suggestion and try make extraclean.
