selftests/nolibc: stop testing constructor order
The execution order of constructors in undefined and depends on the
toolchain. While recent toolchains seems to have a stable order, it
doesn't work for older ones and may also change at any time.
Stop validating the order and instead only validate that all
constructors are executed.

tools/nolibc: add support for 32-bit s390
32-bit s390 is very close to the existing 64-bit implementation.
Some special handling is necessary as there is neither LLVM nor
QEMU support. Also the kernel itself can not build natively for 32-bit
s390, so instead the test program is executed with a 64-bit kernel.

tools/nolibc: add support for directory access
Add an implementation for directory access operations.
To keep nolibc itself allocation-free, a "DIR *" does not point to any
data, but directly encodes a filedescriptor number, equivalent to "FILE *".
Without any per-directory storage it is not possible to implement
readdir() POSIX confirming. Instead only readdir_r() is provided.
While readdir_r() is deprecated in glibc, the reasons for that are
not applicable to nolibc.
