Friendly ping for an Ack of patch 3 of this series.
After that I'd like to submit an updated nolib
strerror() is commonly used.
For example in kselftest which currently needs to do an #ifdef NOLIBC to
handle the lack of strerror().
Keep it simple and reuse the output format of perror() for strerror().

The implementation always works on uintmax_t values.
This is inefficient when only 32bit are needed.
However for all functions this only happens for strtol() on 32bit

The series adds support for setrlimit/getrlimit.
Mainly to avoid spurious coredumps when running the tests under
qemu-user.

tools/nolibc: drop custom definition of struct rusage
tools/nolibc: add support for getrlimit
A future commit will include linux/resource.h, which will conflict with
the private definition of struct rusage in nolibc.
Avoid the conflict by dropping the private definition and use the one
from the UAPI headers.

When an architecture is unsupported arch.h would silently continue.
This leads to a lot of followup errors because my_syscallX() is not
defined and the startup code is missing.
Avoid these confusing errors and fail the build early with a clear
error message and location.
