Thanks Yang, and Toby. Both methods work fine.
I ended up using the single pass method. I had to do the following changes:
Changed the contents of include/curl/curlbuild.h to
#ifdef __LP64__
#include "curlbuild64.h"
#else
#include "curlbuild32.h"
#endif

where curlbuild64.h and curlbuild32.h were created by running configure separately for x86_64 and i386 architecture. Also, applied the following patch:
