[PATCH] newlib/libc/include/sys/features.h: Update RTEMS section

[Joel Sherrill]

This was posted on Oct 3 and there has been no feedback. OK to commit?

Also https://sourceware.org/pipermail/newlib/2025/022120.html is v3 of a
patch to setjmp.h. v3 was also posted on 3 Oct.

I hope everyone is doing well. This delay is not usual for newlib.

Thanks.
