## We are intentionally building an executable here instead of a dylib / bundle
|
|
## in order that the `__PAGEZERO` segment is present, which in turn means that
|
|
## the image base starts at a non-zero address. This allows us to verify that
|
|
## addresses in the export trie are correctly encoded as relative to the image
|
|
## base.
