update gcc-9 and gcc-10 packages for focal

[Matthias Klose]

As done for gcc-7 and gcc-8 in 18.04 LTS in LP: #1848319, I'd like to update the gcc-9 and gcc-10 packages in focal to the final 10.2.0 release.

 - gcc-10, update to the gcc-10.2.0 release
 - gcc-9, update to the gcc-9 release branch to the time
   of the gcc-10 release.
 - corresponding gcc-cross packages

The package builds are prepared in
https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/ppa/+packages

[Impact]
Provide an upstream release for GCC 10.2, and an update for GCC 9 to the 9.3 branch

[Regression Potential]
There is regression potential, however with a test rebuild of the main portion of the archive no regressions were found.

[Test Case]
No regressions in the GCC test suite, and no regressions in the test
rebuild of the main component of the archive (all architectures)

As a test, a complete archive rebuild was performed, and no regressions were found with this new package. The archive rebuild also contained updated versions of gcc-9, gcc-10, python3.8, and python3-stdlib-extensions. The GCC and Python packages should not infer with each other.

[Validation]
Analyze the build logs for regressions.
For the cross builds, just make sure that the packages build using
the updated sources.

Summary of the test rebuilds:
https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20200810-focal-focal.html
https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20200810-focal-gcc-focal.html

The first one is a reference build, the second one the test rebuild with the updated components.

There are no additional regressions except for pyxdg, which is unrelated to the GCC update, and which was fixed by a separate SRU. Note that the riscv64 builds are purely informational, and are not checked for any regressions.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Lastique (andysem)]

At this point it might be worth updating gcc-10 to 10.2.

I'm particularly interested in gcc-10 upgrade because I might be affected by a g++ bug that is already fixed in a more recent version of gcc-10. I cannot upgrade locally because the problem appears in a public Travis CI instance.

Thank you!

The testing was already done before the acceptance to -proposed. See the bug description.

[Alberto Milone (albertomilone)]

The update seems to break the NVIDIA packages, any ideas?

See the full log in the attachment.

These are the last two lines:
E: Could not configure 'libc6:i386'.
E: Could not perform immediate configuration on 'libgcc-s1:i386'. Please see man 5 apt.conf

I can't reproduce the problem any more here, either on my Focal installation or in my chroot.
