Error while compiling arm-lwt

Hello,

I'm derived arm-lwt from your repository, but I trying to cross-compile it by other suite (Yocto's arm-oe-linux-gnueabi).
I see the following error:

- + /mnt/opam/4.02.1/bin/arm-oe-linux-gnueabi-ocamlfind ocamlc -ccopt -I/usr/include -ccopt -I/usr/include -ccopt -Isrc/unix -c src/unix/lwt_unix_stubs.c

Setting environment variables CC,LD and CPP to point to correct programs with "--sysroot=..." has ho effect for setup.ml.
How can I set something like "--sysroot=..."option for gcc in opam file (i.e. sa setup.ml's command line argument) or maybe in ocamlfind arguments?
Also, setting environment variables CC,LD and CPP to point to correct programs with added "--sysroot=..." has ho effect for arm-lwt's setup.ml.
I.e. I see in config output:

- bytecomp_c_compiler: ................................. gcc -fno-defer-pop -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT -fPIC
- native_c_compiler: ................................... gcc -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT

Is it right, that in your environment with NDK, gcc uses "--sysroot=..." to correctly cross compile stubs?
Can you point me to some way how you solved such problems with stubs?

Packages required to compile on Ubuntu 13.04

I recommend putting in the Readme that installing ia32-libs can help with installing some of the OPAM packages in this repository on 64-bit Ubuntu installations. The compilation was failing with a "libz.so.1 not found" error before I installed ia32-libs.

base-threads is missing

Seems like base-threads is missing in the repository. Is it intended?

How to compile for x86?

I was able to build shared objects for ARM architecture. I use the following commands (sort of):

ocamlfind -toolchain android ocamlopt -c prog.ml
ocamlfind -toolchain android ocamlopt -o libprog-jni.so -shared prog.o prog-jni.c

I pack libprog-jni.so in *.apk and Dalvik loads it and everything is fine.
However, I can't build the object for x86 CPU because my system is AMD64.
Is it possible to do using your tool?
