[svn-r12929] Hopefully this really is a fix for the tg-login errors.

The version of libtool used by HDF5 isn't directly affected by the reconfigure
script; instead, libtoolize --force must be used by hand.  Libtool was the
source of the problem, so rolling its version back to 1.5.14 should solve the
issue (at least temporarily).

Reconfigure should still work on both heping and kagiso.

Tested on heping, kagiso, and tg-login3.
