I found the relationship. The ancient Solaris version of libgcrypt
contains a globally available copy of strsep. So that is where the
build has been comming up with that function.

So, at least for now, add '-lgcrypt' as the last entry of the definition
of the LDFLAGS environment variable when running configure.

Note that the patch is perfectly correct in removing all uses of
libgcrypt as the setup that was previously attempted can not be
done with the ancient Solaris version of libgcrypt.
