svn commit: r338191 - head/usr.sbin/amd/libamu

New Revision: 338191
URL: https://svnweb.freebsd.org/changeset/base/338191

Log:
  Use unifdef -x1 instead of ignoring the shell exit code
  
  This way the target fails if unifdef doesn't exist or doesn't modify the
  file instead of just generating an empty .c file.
  I found this while building without inherited $PATH (D16815)
