/* Note [Static Build On Linux]
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* The default `glibc` contains a bug that would cause crashes when downloading
* files form the internet, which is a crucial Launcher functionality. Instead,
* `musl` is suggested by Graal as an alternative libc. The sbt task
* automatically downloads a bundle containing all requirements for a static
* build with `musl`.
*
* The `musl` bundle that we use is not guaranteed to be maintained, so if in
* the future a new version of `musl` comes out and we need to upgrade, we may
* need to create our own infrastructure (a repository with CI jobs for creating
* such bundles). It is especially important to note that the libstdc++ that is
* included in this bundle should also be built using `musl` as otherwise linker
* errors may arise.
*
* Currently, to use `musl`, the `--libc=musl` option has to be added to the
* build and `x86_64-linux-musl-gcc` must be available in the system PATH for the
* native-image. In the future it is possible that a different option will be
* used or that the bundle will not be required anymore if it became
* prepackaged. This task may thus need an update when moving to a newer version
* of Graal.
*
* Currently to make the bundle work correctly with GraalVM 20.2, a shell script
* called `x86_64-linux-musl-gcc` which loads the bundle's configuration is created by the
* task and the paths starting with `/build/bundle` in `musl-gcc.specs` are
* replaced with absolute paths to the bundle location.
