- Utilize standard means for installing files and symlinks.
- Utilize standard means for installing files and symlinks.

- Simplify the symlink list construction by implementing a
  generic mechanism to map LC_MONETARY files from one locale
  to another, possibly with a different <lang>_<territory>
  components of the locale name.  Example:

    ENCODING-1_ENCODING-2= fo_BA fo_FO:ba_BA

  in Makefile will result in the following symlinks:

    fo_BA.ENCODING-1/LC_MONETARY -> fo_BA.ENCODING-2/LC_MONETARY
    fo_FO.ENCODING-1/LC_MONETARY -> ba_BA.ENCODING-2/LC_MONETARY

- Install LC_MONETARY files with mode 444.

- While here, fixed trashing of the sr_YU.UTF-8/LC_MONETARY
  file by a symlink, and removed one duplicate symlink.
