I can build the tree with compiler-rt with both x86-64 and i686, on centos5.

* Make sure to install gcc44-c++ and libstdc++44-devel.{x86_64|i386}
* Specify to configure, CC=gcc44 CXX=g++44

When clang and compiler-rt would be built as i686 on x86-64 host;

$ /path/to/configure 'CC=gcc44 -m32' 'CXX=g++44 -m32'

--build is mandatory, or configure would not know it is built for i386, and
llvm/test/ExecutionEngine would fail.

I have not checked anything on i686 host.
