-Subject: [PATCH] mutex: Fix build on 32-bit architectures using 64-bit time_t
-
-mutex code uses SYS_futex, which it expects from system C library.
-in glibc (/usr/include/bits/syscall.h defines it in terms of of NR_futex)
-rv32 is using 64bit time_t from get go unlike other 32bit architectures
-in glibc, therefore it wont have NR_futex defined but just NR_futex_time64
-this aliases it to NR_futex so that SYS_futex is then defined for rv32
