Also fix DEPENDS on gettext for native casea -- this is to fix the
following failure(that occasionally occurs in my local tests):
configure.in:44: warning: AM_NLS is m4_require'd but not m4_defun'd
| aclocal.m4:1826: IT_PROG_INTLTOOL is expanded from...
| configure.in:44: the top level
| configure:3327: error: possibly undefined macro: AM_NLS
Also remove a trailing space char in LIC_FILES_CHKSUM.
