+Subject: [PATCH] fiber,libs: Define SYS_futex if it does not exist
+
+__NR_futex is not defines by newer architectures e.g. arc, riscv32 as
+they only have 64bit variant of time_t. Glibc defines SYS_futex interface based on
+__NR_futex, since this is used in applications, such applications start
+to fail to build for these newer architectures. This patch defines a
+fallback to alias __NR_futex to __NR_futex_tim64 so SYS_futex keeps
+working

[PATCH 2/2] mesa: Fix build on 32bit arches supporting 64bit time_t only

[Khem Raj]

Fixes
../mesa-20.1.8/src/util/futex.h:47:19: error: use of undeclared identifier 'SYS_futex'; did you mean 'sys_futex'?
   return syscall(SYS_futex, addr1, op, val1, timeout, addr2, val3);
                  ^~~~~~~~~
