gcc-11 11-20210317-0ubuntu1 source package in Ubuntu

Changelog

gcc-11 (11-20210317-0ubuntu1) hirsute; urgency=medium

  * GCC snapshot, taken from the trunk (20210317)
  * Also build unstripped frontends on mipsel/mips64el.
  * Update libgphobos symbols file.
  * Don't remove files in debian/tmp-{nvptx,gcn} when building the binary
    targets. The installed offload compilers are needed to run the tests.
  * Allow to save some disk space for the build, by
    - saving the files needed for the hppa64 and jit builds, and removing
      the build directories.
    - saving the results from the check runs, and removing files created
      during the check runs.

gcc-11 (11-20210313-0ubuntu1) hirsute; urgency=medium

  * GCC snapshot, taken from the trunk (20210313)
  * Run the testsuite during the build.

gcc-11 (11-20210310-2) UNRELEASED; urgency=medium

  * Fix --as-needed specs for -fsanitize=* options for backports.
  * Export DEB_CHECK_ALI_UPDATE=1 (currently commented out). This should be
    checked after the gnat transition has been prepared in experimental, and
    just before doing the gnat's defaults change in unstable.
  * debian/ada/check_ali_update.sh: Fix syntax errors.
    Always run the script.
  * Disable building gnat on alpha, see PR ada/98724.
