I am trying to build my 64 bit libraries on a 32 bit host and almost
got it right. I can build correctly with gcc when adding -m64 on the
commandline, so the libraries are all there. But when I build using
boost build, the I get the following error :

/usr/bin/ld: /home/bj/sulum/external/boost/bin.v2/libs/thread/build/gcc-4.4.1/release/address-model-64/link-static/threading-multi/libboost_thread.a(thread.o):
relocation R_X86_64_32 against `tls_destructor' can not be used when
making a shared object; recompile with -fPIC
/home/bj/sulum/external/boost/bin.v2/libs/thread/build/gcc-4.4.1/release/address-model-64/link-static/threading-multi/libboost_thread.a:
could not read symbols: Bad value
collect2: ld returned 1 exit status

I don't think it has any thing to do with thread library, I am missing
something.

But all files are being compiled with -fPIC, so I am a bit stuck, any
pointers appreciated ?
