s390: always set -march compiler option
Currently we only set the -march compiler option if the kbuild system figured out that the compiler actually supports the selected architecture (cc-option test). In result this means that no -march compiler option is set when an unsupported cpu architecture of the current compiler is selected. The kernel compile will afterwards succeed but with the default architecture instead of the (unsupported) selected one. Change this behaviour, so compiles will fail if the compiler does not support the selected cpu architecture.
