Big static array causes rlib to bloat in size

[nebulark]

A big static array inside a library causes the generated lib file to bloat in size, even if it is zero initialized.
I tried this code:

static BUFFER : [u8; 1 << 29] = unsafe { std::mem::zeroed() };

I would expect that this would not affect the size of library.
Instead this causes the library to include a LOT of 0s, increasing the size in this example to over 1GB.
The final executeable is unaffected, only the .rlib file bloats.

This happens in stable and nightly
