pc-bios/s390-ccw: build for z900

Browse source 
Newer distributions have an architecture level set to z9, z196
or similar - also as default option for the compiler.

We should build the bios for z900 to allow it to run with
all 64bit CPUs. This will become more important as soon as
QEMU/KVM does support CPU models.
