This change adds the AT_BASE entry (which contains the base address of the interpreter for the user program, or zero if there is no interpreter) to the auxiliary vector that is set up on the user stack when executing the program. This is needed by the musl dynamic linker, which would otherwise calculate a wrong base address during startup, resulting in a segmentation fault.
