Hi All.
Given my recent bump to gettext 0.19.7 libxml2 is now required more than 
ever for the new ITS handling code.
The problem now is that older libxml2 versions might not be enough for 
host-gettext and result in build failure:
http://autobuild.buildroot.net/results/1b7/1b7b1244ccab111dbcdb6350525077d2a7157d91/build-end.log

It is silly that the configure script doesn't check for this, however we 
can't make conditionals for host packages (or better said, for things 
that may or may not be present in the distro), and i follow the same 
line of reasoning of avoiding bundled duplication - it's more a matter 
of build time than space for host packages, but still.

I'd vote for making it so as well.

Regards.
