Comment (by acjones8):

 Ran into this issue today while upgrading coreutils on 10.5.8. If I try to
 do it with gcc-4.2, it fails and gets stuck trying to recreate the same
 directory inside itself until it eventually hits the limit for the longest
 possible filename and fails. This probably isn't a proper fix, but as a
 short term workaround, using gcc-7.5.0 instead gets through the compile
 without any problems.
