I regenerated all target description .c files from scratch, and got
this spurious diff.
It's a simple mid-air collision - these files were clearly generated
before commit 73b4f516a0 ("maint_print_c_tdesc_cmd: Use type for
TYPE_CODE_FLAGS instead of field_type."), which did the global
s/field_type/type/, and pushed to master afterwards.
