Also remove option static_llvm and add option bindist, which helps simplify building bootstrap tarballs.

Subject: [PATCH 13/15] round result of (highest as f64).log(2.0)
|
|
|
|
Even though (1024f64).log(2.0) has an exact, representable, value, with
|
|
rustc 1.32 on i386 it comes out as +9.999999999999999985 with
|
|
optimization enabled. And the rustc doesn't like having two defintions
|
|
for U1024 etc.
