zstd-1.4.4-1.6.1 RPM for aarch64

From OpenSuSE Leap 15.3 for aarch64

Name: zstd Distribution: SUSE Linux Enterprise 15
Version: 1.4.4 Vendor: SUSE LLC <>
Release: 1.6.1 Build date: Fri Mar 12 17:27:47 2021
Group: Productivity/Archiving/Compression Build host: ibs-arm-2
Size: 1392842 Source RPM: zstd-1.4.4-1.6.1.src.rpm
Summary: Zstandard compression tools
Zstd, short for Zstandard, is a lossless compression algorithm. Speed
vs. compression trade-off is configurable in small increments.
Decompression speed is preserved and remains roughly the same at all
settings, a property shared by most LZ compression algorithms, such
as zlib or lzma.

At roughly the same ratio, zstd (v1.4.0) achieves ~870% faster
compression than gzip. For roughly the same time, zstd achives a
~12% better ratio than gzip. LZMA outperforms zstd by ~10% faster
compression for same ratio, or ~1–4% size reduction for same time.

  - Add baselibs.conf: libarchive gained zstd support and provides
    - 32bit libraries. This means, zstd also needs to provide -32bit
* Fri Jun 14 2019
  - Remove googletest-devel BuildRequires and pzstd-global-gtest.patch
    because we want zstd in ring0 (due to rpm's zstd payload support)
    Since googletest is only used in build time (it's for testing after
    all), this should be fine.

    quite some applications.
* Sat Jan 05 2019
