Title:
  libphobos: std.net.curl does not understand HTTP/2 status lines

Status in gcc-10 package in Ubuntu:
  Fix Released
Status in gcc-10 source package in Focal:
  Fix Committed

Bug description:
  The GDC runtime access to the libcurl is broken. CURL operations abort
  with unexpected error codes.

  Test programm:
  ```
  import std.net.curl;
  import std.stdio;

  void main()
  {
      HTTP http = HTTP();
      auto data = get("https://acme-staging-v02.api.letsencrypt.org/directory", http);
      writeln(data);
  }
  ```
  Compile this program and run it.
  $ gdc curldownload.d -o curldownload -g
  $ ./curldownload
  std.net.curl.HTTPStatusException@/usr/lib/gcc/aarch64-linux-gnu/10/include/d/std/net/curl.d(1071): HTTP request returned status code 0 ()

  The same issue also impacts the 'dub' package. It is *not* possible to
  update/fetch packages from code.dlang.org.

  I compiled 'ldc2' from sources in its latest version. The code snippet
  works fine, when compiled with ldc- Also 'dub', when recompiled with
  ldc2, works fine.

  So there is some problem with gdc and its access to libcurl. Maybe
  broken library bindungs? Some issue with ARM32 and ARM64 archs (same
  problem with ARM32(gnueabihf))?

  Issue also reported on dlang.org :
