APT Repository Update (build-2020-01-10)

[Tony Theodore]

Hi All,

The repository has been updated to tag `build-2021-01-10`[1] for the
following distros[2]:

  - Debian 9 Stretch
  - Debian 10 Buster
  - Ubuntu 16.04 Xenial
  - Ubuntu 18.04 Bionic
  - Ubuntu 20.04 Focal

Ubuntu 14.04 Trusty is available at 20190309, but will be removed soon.

The build matrix[3] shows package/target support (takes some time to
render styling), and deb packages were built with the following
`settings.mk`:
  MXE_USE_CCACHE := no
  EXCLUDE_PKGS = ocaml%
  gdal_CONFIGURE_OPTS = --with-openjpeg=no

Logs:
  https://pkg.mxe.cc/repos/build-logs/

Related issues:
  ccache #2349[4] fixed for deb building - open for general approach
  ocaml* #2512[5] need to separate luajit and merge
  ffmpeg #2558[6] fixed
  docs   #2535[7] in progress

Quick start:
  sudo apt-get -y install software-properties-common lsb-release
  sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 86B72ED9
  sudo add-apt-repository "deb [arch=amd64] https://pkg.mxe.cc/repos/apt 
`lsb_release -sc` main"
  sudo apt-get -y update
  sudo apt-get -y install mxe-<target>-<package>

Note all package and target names have underscores `_` replaced with
dashes `-` i.e:
  x86_64-w64-mingw32 sdl_sound --> mxe-x86-64-w64-mingw32.static-sdl-sound  

See lightspark project for CI build example[8].

Cheers,

Tony
