You're picking up the assembler for your host machine, not the cross-assembler
for your target.
When you run configure, make sure that your target binutils are in the PATH.
Alternatively, you can use --with-ld=, --with-as=, etc.
The output of configure will tell you which ld, as, etc. it's using. Make sure
these are the target versions.
