The output reported may be locale-dependent, which results in unreproducible builds.

$ LANG=C ld --version | head -n 1 GNU ld (GNU Binutils for Debian) 2.26

$ LANG=it_CH.UTF-8 ld --version | head -n 1 ld di GNU (GNU Binutils for Debian) 2.26

Forcing LC_ALL=C ensures the output is consistant regardless of the build environment.

Thanks to HW42 for debugging the issue:
