This commits needs a MAJOR audit as I oftentimes just guessed which of `$hostOffset`, `$targetOffset`, or a fixed offset should be used.

# On macOS, frameworks are linked to the system CoreFoundation but
|
|
# dynamic libraries built with nix use a pure version of CF this
|
|
# causes segfaults for binaries that depend on it at runtime. This
|
|
# can be solved in two ways.
|
|
# 1. Rewrite references to the pure CF using this setup hook, this
|
|
# works for the simple case but this can still cause problems if other
|
|
# dependencies (eg. python) use the pure CF.
|
|
# 2. Create a wrapper for the binary that sets DYLD_FRAMEWORK_PATH to
|
|
# /System/Library/Frameworks. This will make everything load the
|
|
# system's CoreFoundation framework while still keeping the
|
|
# dependencies pure for other packages.
