This is the first step in preparation for:

[libc][NFC] Cleanup code for poll (#141802)

2025-05-28T21:08:47+00:00

Ensure everything is defined inside the namespace, reduce number of
ifdefs.

[libc] Enable poll function for riscv (#139180)

2025-05-13T21:59:28+00:00

RV32 uses SYS_ppoll_time64 instead of SYS_ppoll, but the call is the
same.

[libc][poll] remove entrypoint for riscv (#125941)

2025-02-05T21:56:30+00:00

riscv32 specifically doesn't provide EITHER SYS_poll or SYS_ppoll. We may be
able to reimplement poll in terms of syscalls to SYS_ppoll_time64, but will
leave that as a TODO for the future. (Such as when we want to be able to cross
compile for riscv32).
