The previous version of "intl" was built as a static library.  Configure in
the older package had the option --enable-host-shared,
which I did not use.  Based on the failure message, the in-tree gettext
seems to be built as a shared library.  If you explicitly
pass --disable-shared to the in-tree configure, you may get farther.  I'm
currently using --disable-shared --disable-threads.
As we have discussed, the current gettext will retain some references to
pthreads despite the configure option.

Thanks, David
