Patch to support libxml on FreeBSD

[Kim Shrier]

With all the recent changes to the makefiles, the headers for libxml
are no longer found since FreeBSD puts them in a non-standard location.
In order to allow both version 1.x and 2.x of libxml to be on the same
machine, the headers for libxml are placed in
/usr/local/include/libxml2/libxml.  Also, since some of the time the
headers are included as "tree.h" and sometimes as "libxml/tree.h"
both /usr/local/include/libxml2 and /usr/local/include/libxml2/libxml
need to be in the include path.  This patch fixes configure.in in
core/make.  After applying this patch, you will need to regenerate the
configure script.
