[xml] AIX 4.3.2 core

["Wilson, Douglas" <dgwilson sonomasystems net>]

At first I built libxml2, installed it, built libxslt, and installed it
also, then
ran into problems with libxslt core dumping. libxslt dumped core on
every test ( I hadn't yet done make test on libxml2). I found a suggestion
to
use './configure --disable-shared' when building, so I rebuilt libxslt and
it passed most tests (dumping core on a few).

Then I noticed that libxml2 was dumping core on 3 of the tests, but
when I tried to rebuild with '--disable-shared' I got this on the 'make':
creating libxml2.la

(cd .libs && rm -f libxml2.la && ln -s ../libxml2.la libxml2.la)

cc -DHAVE_CONFIG_H -I. -I. -I. -I./include -I./include       -g -c xmllint.c

/bin/sh ./libtool --mode=link cc  -g  -o xmllint  xmllint.o ./libxml2.la

cc -g -o xmllint xmllint.o  ./.libs/libxml2.a -liconv -lm

It builds fine if I configure without any options, but it segfaults on
the testing floats/functions/strings part of the XPath regression
tests, and the xslt library seems somewhat useable (though I'm not
sure when its going to dump core).
