Comment (by cal@…):

 If we did that for all our incovations of `AC_ARG_VAR` that would add
 another 17 possible arguments. I don't think this is the way to go.

 The list would be:
  - BSDMAKE
  - BZIP2
  - CVS
  - GNUMAKE
  - GNUTAR
  - LZMA
  - MAKE
  - MTREE
  - OPEN
  - OPENSSL
  - RSYNC
  - SED
  - SVN
  - SWIG
  - TAR
  - XAR
  - XZ
