binutils 2.30 still breaks rust builds on sparc64
Hi!
binutils 2.30 has unfortunately still at least two issues on sparc64 which become
visible when trying to build rust code. Both issues do not exist with 2.28.
When trying to build rustc from git natively using a known to work rustc
compiler that was cross-built, I get:

Downgrading binutils to 2.28 fixes this issue.
A second problem occurs when trying to cross-build the rust compiler for sparc64 on x86_64:
error: linking with `sparc64-linux-gnu-gcc` failed: exit code: 1

This is also fixed by downgrading binutils to 2.28. I have reported this issue upstream [1].
