[PATCH v5 01/15] objtool: Fix generic annotation infrastructure cross build

[Christophe Leroy]

Cross build for powerpc/32 on x86_64 leads to:

  CC      init/main.o
init/main.o: warning: objtool: early_randomize_kstack_offset+0xf0: Unknown 
annotation type: 134217728
init/main.o: warning: objtool: start_kernel+0x4a8: Unknown annotation type: 
134217728
init/main.o: warning: objtool: do_one_initcall+0x178: Unknown annotation type: 
134217728

Fix byte order.
