textproc/libxml2 2.7.8
	
>Description:
After upgrade to libxml2-2.7.8, programs depending on lilbxml2 fail with
errors like
/libexec/ld-elf.so.1: /usr/local/lib/libxml2.so.5: version LIBXML2_2.5.7 required by /usr/local/bin/epiphany not defined

As Andrey Ponomarenko observed, this is a bug in libxml2's configure
script, fixed upstream in
http://git.gnome.org/browse/libxml2/commit/?id=00819877651b87842ed878898ba17dba489820f0
Attached patch fixes this for the port.

Note: this obsoletes ports/152612

>How-To-Repeat:
Obvious.

>Fix:
