libzstd_1.3.4+dfsg.orig.tar.xz is only available in NEW

=> once libzstd_1.3.4+dfsg-1 and just pushed libzstd_1.3.4+dfsg-2 have
passed new the fix should be available.

Kind regards

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!
