--- Comment #1 from kinke at gmx.net ---
This list should strive not to grow too much. musl is already detectable via
`CRuntime_Musl`, as is uClibc and glibc. So if e.g. the Void distro isn't
anything special wrt. kernel and libc, there's no need for a dedicated
predefined version. We'd have thousands of versions for all distros otherwise.
