Build fails on Linux

Created by: timp3289

Hi, Build is failing for me from the latest source straight from Git. I have the latest Rust version:

$rustc -V   rustc 1.6.0-dev (edf2198f5 2015-11-25)

The Git repo is unmodified and up to date

$git status On branch master Your branch is up-to-date with 'origin/master'. nothing to commit, working directory clean

I ran make clean first

$make clean   rm -rf build filesystem/.bin filesystem/.list filesystem/apps//.bin filesystem/apps//.list filesystem/schemes//.bin filesystem/schemes//.list

Running make virtualbox or make qemu gives the same result This error is repeated several times:

rust/librustc_unicode/u_str.rs:132:1: 132:74 error: The attribute deprecated is currently unknown to the compiler and may have meaning added to it in the future (see issue #29642)

Log files from make, along with compiler errors, are attached. make_virtualbox_log.txt make_qemu_log.txt
