As "s39032" would look horrible, use the another naming scheme.
32-bit s390 is "s390" and 64-bit s390 is "s390x",
similar to how it is handled in various toolchain components.

This reverts commit 16767502aa990cca2cb7d1372b31d328c4c85b40.
Nolibc gained support for uname(2) and sscanf(3) which are the
dependencies of ksft_min_kernel_version().
So re-enable support for ksft_min_kernel_version() under nolibc.

Changes in v2:
- Return __LINE__ from different testcases to directly point to the
failed testcase
- Add some comments
- Expand commit message
- Link to v1:
https://lore.kernel.org/r
These functions are used often, also in selftests.
sscanf() itself is also used by kselftest.h itself.

The list is getting overly long and any modifications introduce a lot of
noise and are prone to conflicts. Split the string into a bash array
and break that into multiple lines.

These structs are never modified, move them to read-only memory.
This makes the API clearer and also prepares for the constification of
'struct attribute' itself.
While at it, also constify 'modinfo_attrs_count'.

The structure is always read-only due to its placement in the read-only
section __modver. Reflect this at its usage sites.
Also prepare for the const handling of 'struct module_attribute' itself.

params: Prepare for 'const struct module_attribute
The 'struct module_attribute' sysfs callbacks are about to change to
receive a 'const struct module_attribute *' parameter.
Prepare for that by avoid casting away the constness through
container_of() and using const pointers to 'struct param_attribute'.

Not all architectures implement lseek(), for example riscv32 only
implements llseek() which is not equivalent to normal lseek().
Remove the need for lseek() by using a pipe instead.

Newer archs like riscv32 don't provide waitpid() anymore.
Switch to waitid() which is available everywhere.

The riscv32 architecture is missing many of the older syscalls.
Instead of providing wrappers for everything at once, introducing a lot
of complexity, skip the tests for those syscalls for now.
