[racket] compiling Racket to android and ios apps

I installed the Command Line Tools for XCode (for Mavericks).
Then I tried using the options above for the simulator build.
The configuration fails - I think it is using the wrong C compiler?

mba-5:src soegaard$ ./configure --host=x86_64-apple-darwin

Here is config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.69.  Invocation command line was
