[Debian-med-packaging] Bug#895259: libzstd: FTBFS on riscv64: undefined reference to `__atomic_compare_exchange_1'

[Adam Borowski]

Source: libzstd
Version: 1.3.3+dfsg-1
Severity: normal

Hi!
Here's a patch to fix FTBFS on riscv64.

Submitted upstream as https://github.com/facebook/zstd/pull/1103, but as
this library has some interesting rbdeps, it'd be nice if you could apply
this without waiting for an official release.


Meow!
