Patch for "file" attached. Strangely, it uses "file" in its configure script, but this does not seem to be crucial:
case `/usr/bin/file conftest.o` in
*32-bit*)
case $host in
x86_64-*kfreebsd*-gnu)
LD="${LD-ld} -m elf_i386_fbsd"
;;
x86_64-*linux*)
LD="${LD-ld} -m elf_i386"
;;
ppc64-*linux*|powerpc64-*linux*)
LD="${LD-ld} -m elf32ppclinux"
;;
s390x-*linux*)
LD="${LD-ld} -m elf_s390"
;;
sparc64-*linux*)
LD="${LD-ld} -m elf32_sparc"
;;
esac
;;
*64-bit*)
case $host in
x86_64-*kfreebsd*-gnu)
etc.
