#10783 introduced another definition of a buildnativeimage task. Since that time, our CI is transiently failing on out of memory error. This PR ensures that there can be just a single `buildNativeImage` task running at a time. # Important Notes Manually tested by running ``` sbt:enso> all engine-runner/buildNativeImage project-manager/buildNativeImage ``` And looking at spawn subprocesses. On develop, I have two `native-image` processes, on this PR, there is just a single one.

/* 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.
