[ptxdist] [PATCHv3 03/10] rrdtool: fix libxml2 handling

[Robert Schwebel <r.schwebel@pengutronix.de>]

The configure script searches for the libxml2 headers in /usr/include,
so we remove the hardcoded path here.

The check is searching for xmlParseFile, which is part of the SAX2 API.
This means we need to enable the feature in libxml2.

+Subject: [PATCH] configure.ac: don't specify hardcoded include search path
+
+If we crosscompile rrdtool or packetize for a distribution, libxml2
+headers may be installed in a SYSROOT/DESTDIR directory, not in
+/usr/include. For the cross compile usecase, this leaks a host header
+file in.
