// This test exercises the `bundle` link argument, which can be turned on or off.
// When building a rlib or staticlib, +bundle means that all object files from the native static
// library will be added to the rlib or staticlib archive, and then used from it during linking of
// the final binary.
// When building a rlib -bundle means that the native static library is registered as a dependency
// of that rlib "by name", and object files from it are included only during linking of the final
// binary, the file search by that name is also performed during final linking.
// When building a staticlib -bundle means that the native static library is simply not included
// into the archive and some higher level build system will need to add it later during linking of
// the final binary.
// This modifier has no effect when building other targets like executables or dynamic libraries.
// The default for this modifier is +bundle.
