GHC 6.8.1 port on FreeBSD-amd64?

As I have got an amd64 machine again, I am returning to my previous porting effort. When I try to build to .hc files on i386 system, I get the following error:

... gmake[2]: Entering directory `/usr/home/wb/ghc-6.8.1/libraries/unix' ../../compiler/stage1/ghc-inplace -package-name unix-2.2.0.0 -hide-all-packages -i -idist/build/autogen -idist/build -i. -Idist/build -Iinclude -#include "HsUnix.h" -#include "execvpe.h" -odir dist/build -hidir dist/build -stubdir dist/build -package base-3.0.0.0 -package directory-1.0.0.0 -O -XCPP -XForeignFunctionInterface -idist/build -H32m -O0 -fasm -Rghc-timing -keep-hc-files -O -c dist/build/System/Posix/Process.hs -o dist/build/System/Posix/Process.o -ohi dist/build/System/Posix/Process.hi Prologue junk?: .type s32x_ret, @function s32x_ret: pushl %ebp movl %esp, %ebp

which I don't understand at all. The build of ghc-6.8.1 for native use on a FreeBSD-6.2 i386 did not cause any problems. Perhaps someone else has done the porting work already. Please give me a note, if anybody is able to provide me a set of files to get the bootstrap further. -- Dipl.-Math.
