I guess I don't understand how the "machine=" specification in the
configure scripts work...  They look like file path names that the
build machinery tries one by one like this:

machine=a/b/c/d

step 1) try $(foo)/a/b/c/d
step 2) try $(foo)/a/b/c
step 3) try $(foo)/a/b
step 4) try $(foo)/a

You seem to be suggesting that it works another way.
