A few functions used by different selftests.
Adding them now avoids later conflicts between different selftest serieses.

Also add full support for nolibc-test.c on riscv32.
All unsupported syscalls have been replaced.

As usual, the series looks overall good to me (and I expect it to be
quite useful). I sent a few reminders about not forgetting to include
"nolibc.h" from the other series into the newly added files, though I
guess you have these in mind anyway.

Regardless of the small comments, you can take my ack for the whole
series: Acked-by: Willy Tarreau <w@1wt.eu>

Thanks!
Willy
