Looks like it did, but turned out to have some unintended side-effects
:(.
The snapshot builds are now new:
https://buildfarm.postgresql.org/cgi-bin/show_stage_log.pl?nm=flaviventris&dt=2021-05-10%2015%3A43%3A56&stg=configure
configure:3966: ccache /usr/lib/gcc-snapshot/bin/gcc --version >&5
gcc (Debian 20210421-1) 11.0.1 20210421 (prerelease) [gcc-11 revision
fbb7739892e:d13ce34bd01:3756d99dab6a268d0d8a17583980a86f23f0595a]
But the aforementioned dependencies that needed to remove broke the
installed old versions of gcc/clang.
I started to build the old versions of llvm manually, but that then hits
the issue that at least 3.9 doesn't build with halfway modern versions
of gcc/clang. So I gotta do it stepwise (i.e. go backwards, build llvm
n-2 with n-1), will take a bit of time.
