  Log:
  If "dangerous" environment variables (LD_PRELOAD, LD_LIBMAP,
  LD_LIBMAP_DISABLE, LD_LIBRARY_PATH) are used, then make sure the
  libraries being loaded aren't on a noexec-mounted filesystem.
  
  This is a compromise position: I'm assuming that nobody will be silly
  enough to set the noexec mount flag on part of the default library
  path, in order to avoid adding extra overhead into the common case
  (where those environment variables aren't used).
