WIP: Build some bootstrap elements from git source and update some versions

This merge updates some sources from tar to git, it also updates the versions for bash, glibc and file.

This currently fails to pass the CI tests because of the ABI check, but having experimented I believe this is an error in ABI check. Building file 5.33 from git causes the same "ABI error" even though it's the same version as the tarball.
