bsd-user/elfload.c:1158:15: warning: variable 'mapped_addr' set but not used [-Wunused-but-set-variable]
bsd-user/elfload.c:1165:9: warning: variable 'status' set but not used [-Wunused-but-set-variable]
bsd-user/elfload.c:1168:15: warning: variable 'elf_stack' set but not used [-Wunused-but-set-variable]
