[Buildroot] Buildroot 2021.05 released

Hi,

Buildroot 2021.05 is released - Go download it at:

http://buildroot.net/downloads/buildroot-2021.05.tar.gz

or

http://buildroot.net/downloads/buildroot-2021.05.tar.bz2

Or get it from Git:

git://git.buildroot.net/buildroot

Please give it a spin and report any problems to the mailing list or bug
tracker.

This was another fairly big development cycle with more than 1300
changes all over the tree and 96 unique contributors! I'm once again
very happy to see so many "new" people next to the "oldtimers".

Of noteworthy new features/changes we have:

- FORTIFY_SOURCE, PIC/PIE, RELRO and SSP security hardening options are
  now enabled by default.

- CMake infrastructure: Use CMAKE_EXE_LINKER_FLAGS rather than
  CMAKE_CXX_FLAGS to link with libatomic to fix an compatibility issue
  with poppler. Bump minimal host cmake version to 3.16 (from 3.15) to
  fix a compatibility issue with domoticz.

- Meson: Use correct C++ host compiler (rather than C compiler)

- support/download: Fix tarball generation (from git/svn repos)
  including symlinks pointing to ./<something>. Fix svn download for
  <1.9 clients or repos using CVS-style keywords.

- Infrastructure: Expose CONFIG_DIR to post-build/post-image scripts, so
  they can call the Buildroot Makefile in the correct directory
  for both in-tree / out-of-tree builds.

- support/scripts/gen-missing-cpe: A script to query the list of CPE IDs
  for the packages enabled in the current configuration and:

  - for CPE IDs that do not have any matching entry in the CPE
    database, it emits a warning

  - for CPE IDs that do have a matching entry, but not with the same
    version, it generates a snippet of XML that can be used to propose
    an updated version to NIST.

- support/scripts/cve.py: Use the (significantly) faster yajl2 ijson
  backend for older (< 2.5) ijson versions rather than the slow python
  default, speeding up pkg-stats by ~2x.

- CPE meta data has been added for a large number of packages

- Python{,3}: Fix byte compiling python files with short (single
  character before .py) file names.

- New defconfigs: Acme Systems Acqua A5 (256/512MB), Beagleboard
  BeagleV, Boundary devices Nitrogen8M Plus SOM, NXP i.MX 8M Plus EVK,
  QEMU PPC e500mc

- New packages: beaglev-ddrinit, beaglev-secondboot, janet,
  kodi-inputstream-ffmpegdirect, kodi-vfs-libarchive,
  kodi-visualisation-matrix, libxcrypt, libqrtr-glib, log4qt, mawk,
  perl-parse-yapp, postgis, protozero, python-flask-wtf, python-iwlib,
  python-semantic-version, python-setuptools-rust, python-toml,
  riscv64-elf-toolchain, siproxyd, uftrace, zfs

And the usual package version updates and bug fixes. See the CHANGES
file for details:

The next release will be 2021.08. Expect the first release candidate at
the beginning of August and the final release at the end of the month.

This release will be supported with security and other important fixes
until 2021.08 is out. For longer support, consider our long term support
release (2021.02.x) instead, which will be supported until April 2022.
