-Subject: [PATCH] Fix build on riscv32
-
-Define __NR_mmap in terms of __NR_mmap2 and __NR_futex interms of
-__NR_futex_time64 for rv32, since there calls dont exist for rv32
-
-Also recognise rv32 as a new 32bit platform
-
-Upstream-Status: Submitted [https://github.com/abseil/abseil-cpp/pull/675]
