```
macho: synthesising __mh_execute_header needs to work with incremental

Prior to this change, the routine would assume it is called first,
before any symbol was created, thus precluding an option that in the
incremental setting, we might have already pulled a suitably defined
and exported symbol that could collide and/or be replaced by the
symbol synthesised by the linker.
