svn commit: r358291 - head/usr.sbin/config

Log:
  Create ../compile
  
  Give up the battle to keep extra files in $MACHINE/compile to keep the file in
  the tree. Instead, create CDIR (usually ../compile) if it doesn't exist when
  we're using a default build location (eg, not using -d). If it does, we do
  nothing. This only affects people that do old-school builds, but it's bit me a
  dozen times since last summer so time to fix the bug.
