# Meson currently only handles pie as a boolean for now, so if the user

# What about linker flags? For a static build, no PIE is implied by -static
# which we added above (and if it's not because of the same specs patching,
# there's nothing we can do: compilation will fail, report a bug to your

# instead, we can't add -no-pie because it overrides -shared: the linker then
