MFH: r567263

Back port part of r566296 | gerald | 2021-02-22 from lang/gcc9-devel:

  [B]ack port of part of r565301 | gerald | 2021-02-15 from
  lang/gcc11-devel:

    Explicitly build --without-zstd such that archivers/zstd isn't pulled
    in inadvertedly when present in the build system even though it is not
    an explicit dependency. [1]

Back port part of r566885 | gerald | 2021-03-01 from lang/gcc9-devel:

  Remove the GRAPHITE option. Graphite still is a largely experimental
  feature, so better left to newer versions of GCC such as GCC 10 which
  is now our default.
