hamt tests: Fix link error

[Bruno Haible]

On FreeBSD 13.0, a gnulib testdir produces this link error:

cc -ferror-limit=0  -g -O2  -L/home/bruno/lib -L/usr/local/lib -o test-hamt 
test-hamt.o libtests.a ../gllib/libgnu.a libtests.a ../gllib/libgnu.a 
libtests.a  -lm -lm -lm -lm -lm -lm -lm -lm -lm -lm -lm
ld: error: undefined symbol: libintl_gettext
>>> referenced by xalloc-die.c:34 (../../gllib/xalloc-die.c:34)
>>>               xalloc-die.o:(xalloc_die) in archive ../gllib/libgnu.a
>>> referenced by error.c:195 (../../gllib/error.c:195)
>>>               error.o:(error_tail) in archive ../gllib/libgnu.a
cc: error: linker command failed with exit code 1 (use -v to see invocation)

This patch fixes it.
