The problem is your version of binutils.  What is your version? check it 
with "as --version".  CoLinux kernel can compile with the version, you 
find in bin/build-common.sh near the "BINUTILS_VERSION=".  Check it.

In coLinux Source exists some assembler macros with typing "movl %ss", 
they must type as "mov %ss".  The old patch for that was:
