It looks like it is pulling include files from /usr/include which it
shouldn't be doing.

Do you have xml2-config somewhere in the path?
On my system, looking in log/gdal I have:
Checking for xml2-config... no

You could perhaps try adding to gdal.mk the option --without-xml2  and see
if that helps
