Asger Geel Weirsøe d5e1bd5016 Build only the PAM hook on macOS (0.10.2)
The gtklock module is Wayland-only and its GNU ld link flags
(--whole-archive) do not exist on macOS, so the macOS build stopped
there. macOS now builds just the PAM hook and the display binary, which
is all the Homebrew formula installs; libdl is optional (it is part of
libSystem on macOS).
