pub const BUILTINS: &str = "librucc_builtins.a";Expand description
Our own runtime library, which every one of the three lines below carries.
Named once because two callers ask about it by name: the line that puts it on, and
crate::argv::argv when -fno-builtins-lib asks for it to be left off. A second spelling of
the name in the second place is a flag that stops working the day the first one is renamed.
