s390/purgatory: Enforce z10 minimum architecture level

Browse source

The purgatory code is compiled without the -march option. This means the
default architecture level of the compiler is used. This can cause
problems, e.g. if instructions used in inline assemblies are for a higher
architecture level than the default architecture level of the compiler.

Use z10 as minimum architecture level, similar to the boot code, to enforce
a defined architecture level set.
