extern crate libc;

rustc: Use --extern to always override Previously if --extern was specified it would not override crates in the standard distribution, leading to issues like #21771. This commit alters the behavior such that if --extern is passed then it will always override any other choice of crates and no previous match will be used (unless it is the same path as --extern). Closes #21771 2015-01-30 09:48:23 -08:00			`extern crate libc;`
