gnulib tests vs. LDADD

[Eric Blake]

CVS findutils uses gnulib-tool --with-tests when importing.  But on cygwin, 
compilation then fails in the gnulib-created directory:

gcc  -g2 -Wall -Werror   -o test-dirname.exe test-
dirname.o ../gnulib/lib/libgnulib.a 
../gnulib/lib/libgnulib.a(xalloc-die.o): In function `xalloc_die':
/home/eblake/findutils/gnulib/lib/xalloc-die.c:35: undefined reference to 
`_libintl_gettext'
collect2: ld returned 1 exit status
make[4]: *** [test-dirname.exe] Error 1

It looks like gnulib needs to take its own advice when creating the Makefile.am 
for the tests directory, since I noticed the following message from gnulib-tool:

You may need to use the following Makefile variables when linking.
Use them in <program>_LDADD when linking a program, or
in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library.
  $(LIB_CLOCK_GETTIME)
  $(LTLIBINTL) when linking with libtool, $(LIBINTL) otherwise

but see no evidence of libintl being linked into test-dirname.
