Description:
------------
PROBLEM:
When compiling against freetype 2.5.1 it searchs for freetype.h on "$i/include/freetype2/freetype/freetype.h" when the newest version has this file on "$i/include/freetype2/freetype.h".

SOLUTION:
Let's search for the file on both directories replacing (on PHP "configure" file):
if test -f "$i/include/freetype2/freetype/freetype.h"; then

For:
if test -f "$i/include/freetype2/freetype/freetype.h" || test -f "$i/include/freetype2/freetype.h";  then
