Here's the actual failure with findutils:

gcc  -g2 -Wall   -o test-canonicalize-lgpl.exe test-canonicalize-lgpl.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

So it is the mix with xalloc-die that changes the behavior of
test-canonicalize-lgpl to pull in a gettext function.  But what is
stranger is that findutils only wants to use 'canonicalize', not
'canonicalize-lgpl'.  Somehow, the --with-tests option of gnulib-tool is
pulling in canonicalize-lgpl-tests in spite of the fact that findutils
intends to use the gpl version (in particular, with xalloc, which needs
@LIBINTL@).  And for now, there is no canonicalize-tests module, even
though it could reasonably be the same as canonicalize-lgpl-tests.

I'm still not sure how best to fix this.  Maybe instead of directly using
@LIBINTL@ in test_canonicalize_lgpl_LDADD, we instead use another symbol
which expands to empty by default, but which xalloc can define to expand
to @address@hidden
