Series [v2] python3-pyruvate: disable 64 bit atomics for mips | expand

Commit Message

Tim Orling Jan. 18, 2022, 6:56 p.m. UTC 
Use the same approach as librsvg to disable 64-bit atomics on platforms
which have 32-bit pointers or are otherwise not supported.

https://github.com/crossbeam-rs/crossbeam/blob/master/no_atomic.rs

https://doc.rust-lang.org/std/sync/atomic/#portability
"PowerPC and MIPS platforms with 32-bit pointers do not have AtomicU64
or AtomicI64 types."

Signed-off-by: Tim Orling <tim.orling@konsulko.com>

Changes in v2:
  - add the rest of the fixes from librsvg... mipsel, riscv32 et al
