From 09e631419d9763a4ff08b32d9801c12b475d8ec5 Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Wed, 12 Feb 2020 22:22:17 -0800
Subject: [PATCH] syscalls: Check for time64 unsafe syscalls before using them
musl is using 64bit time_t now on 32bit architectures and these syscalls
no longer exist, therefore its better to check for them being available
before using them
