musl-cross-make compile OpenSSL 3.4.0 failed

[travislee89]

crypto/riscvcap.c:85: return syscall(__NR_riscv_hwprobe, pairs, pair_count, cpu_count, cpus, flags); was added in OpenSSL v3.4.0

#define __NR_riscv_hwprobe 258 is defined in /data/riscv64-linux-musl/include/asm/unistd_64.h, but it looks like the compiler didn't include this macro

FYI: The musl version is now compiled using OpenSSL 3.3.2
