acl: fix link error due to libintl

[Bruno Haible]

This fixes a link error of the test-file-has-acl program on Solaris 10 with
gettext installed, with Sun cc. The reason of the link error was that
  - gettext.h contains inline functions pgettext_aux etc. which link against
    libintl's dcgettext() function.
  - Sun cc did not optimize away this inline function when it is not used.
  - So file-has-acl.o depended on libintl_dcgettext.
  - But test-file-has-acl should not need to link against libintl.
