Cannot cross compile 32-bit ROOT on 64-bit machine

Rooters - all my fastest machines are running 64-bit Linux (SL-4.4) and I am trying to use them to build 32-bit ROOT (64-bit ROOT builds fine).

All this is with ROOT v5.14.00f.

So I do "setarch i386 my-build-script.sh" (which runs ROOT's configure, make clean and make) and everything works fine - ROOT's configure is fooled into thinking this is a 32-bit machine, all the ROOT stuff is compiled with "-m32" but linking bombs out because the freetype and pcre libraries are compiled as 64-bit no matter what I do. I guess their configure and libtool magical scripts have to be tought to use "-m32" on 32-bit machines.

Another quirk I think I see is with linking g2root (anything that uses hbook?) - the build scripts seem to grab the 64-bit version of the g2c fortran runtime libraries.

Next time somebody looks at these build scripts, it would be nice to have these problems sorted out (use -m32 when building freetype and pcre; grab the 32-bit fortran run-time libraries).
