For that, the target defaults to position-independent code and position-independent executables (PIE) by default.
PIE binaries need relocation at runtime. This is usually done by the dynamic linker or libc.
You can use `-Crelocation-model=static` to create a position-dependent binary that does not need relocation at runtime.
## Building the target
The target can be built by enabling it for a `rustc` build:
