zlib build not configuring properly with cross compiler, ignores AR?

I am trying to cross-compile zlib for an ARM processor using crosstool-ng, and its resulting compiler `arm-linux-gnueabihf-gcc`. I set the `CC` variable to use the cross compiler, as well as `AR` and `RANLIB`, then I run them with `./configure` as follows: ``` CC=arm-linux-gnueabihf-gcc AR=arm-linux-gnueabihf-ar RANLIB=arm-linux-gnueabihf-ranlib LDSHARED="arm-linux-gnueabihf-gcc -shared -Wl,-soname,libz.so.1" ./configure --shared --prefix=/usr ``` The problem is that it spits out a `Makefile` without the `AR` variable I had set, instead it has `AR` set to libtool, which is for my native Mac machine. Here is what the Makefile has set: ``` AR=libtool ARFLAGS=-o RANLIB=ranlib ``` I can manually edit the Makefile and change `AR=arm-linux-gnueabihf-ar` and `ARFLAGS=rcs` which fixes the build. But that is a hack to me. Here is the configure script: http://pastebin.com/trmJbPKb Does anyone see anything wrong with how I run the configure command?
