[PATCH] Fix syntax for cygwin-cross

[Charles Wilson]

libltdl/m4/argz.m4: Add quotes around variable, which
may contain the multiword value 'guessing no'.
---
argz.m4 has this interesting behavior on cygwin-cross:
        [[case $host_os in #(
         *cygwin*)
           lt_cv_sys_argz_works=no
           if test "$cross_compiling" != no; then
             lt_cv_sys_argz_works="guessing no"
           else

So, on cygwin cross the variable lt_cv_sys_argz_works has a
value that contains spaces.  Thus, without quotes around its
value, 'test' complains that there are too many arguments.

This should probably also go upstream to gnulib.
