Bug #18369	--with-zlib-dir broken

Description:
--with-zlib-dir uncorrectly reports that headers/libs for Zlib are not found in the specified location. This is cause by configure defining a variable INCLUDES before using $ac_link to test existence of the includes and libs. But $ac_link doesn't use INCLUDES. 

I don't think this issue is platform specific... but I am surprised I didn't find any previous report on it.

How to repeat:
Add --with-zlib-dir with a non standard location.

Suggested fix:
My workaround was to add $INCLUDES to CPPFLAGS (which is used by $ac_link).

verified on linux, i renamed the zlib.h in /usr/include and tried to configure
--with-zlib=/path/to/alternative/install and it failed, with /usr/include/zlib.h
in place it succeded
