package/gcc: switch to gcc 11.x as the default
Even if gcc 10.x is still maintained for some time, switch to gcc 11.x
since it has been released since 2021-04-27 and gcc 12.x is available
since "2022-05-10".
We have been having toolchains in the autobuilders with gcc 11.x since
mid-June 2021, so the vast majority of the problems should have
already been solved.
