Add support for pzstd, the multi-threaded implementation of zstd. The pzstd build requires C++ and threads support. On some architectures (e.g., Microblaze, SPARC), it also requires linking against libatomic due to the use of atomic operations. Ensure that -latomic is passed in LDFLAGS during both the build and install phases. Consistently passing LDFLAGS is necessary because the pzstd Makefile re-links the binary during the 'install' target due to its dependency on the static library. Fixes build failures reported with bootlin-microblazeel-uclibc and bootlin-sparc-uclibc toolchains: Pzstd.cpp:(.text+0x17e8): undefined reference to '__atomic_compare_exchange_1' Pzstd.cpp:(.text._ZN5pzstd15BufferWorkQueue3popERNS_6BufferE): undefined reference to '__atomic_fetch_sub_4' For host-zstd, always build pzstd. It just adds a few seconds of build time.

Zstandard, or zstd as short version, is a fast lossless

|
compression algorithm, targeting real-time compression
|
|
scenarios at zlib-level and better compression ratios
|
|
|
|
The selection of other packages will enable some features:
|
|
xz, lz4 and/or zlib will enable support for corresponding
|

compression formats
