Subject: tools/nolibc: use pselect6_time64 if available
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=248ddc80b145515286bfb75d08034ad4c0fdb08e;p=users%2Fdwmw2%2Flinux.git

tools/nolibc: use pselect6_time64 if available

riscv32 does not have any of the older select systemcalls.
Use pselect6_time64 instead.
poll() is also used to implement sleep().
