I took this suggestion and tried pushing a Homebrew formula/package here [1].
I think I chose a wrong name and maybe something like "development kit" would
have been better. However, would it be possible instead to include the *.rb file
in the scripts/ directory? So users of this can generate the development kit in
their environments. I would maintain the script to keep it in sync with the
required glibc version for the latest kernel version.
