Disable usage of setrlimit in rustc_driver

[nielx]

Since Rust 1.27.0 the compiler uses ​setrlimit to (try to) set the stack size. Haiku does not implement setrlimit for this command (according to the documentation). This leads to an error being displayed each time rustc is invoked.

Although the error is not fatal, it would be nicer not to display it.

The PR should be rewritten. New patch is on its way.
