commit 8993d9663606eeb075725daa669482d428d2356d
Author: Marius Bakke <marius@gnu.org>
AuthorDate: Sun Jan 9 12:26:50 2022 +0100

    gnu: zig: Build with LLD 12.
    
    This fixes a regression introduced in 
a05e573d60bf64129abf4d4e5f27355c84ebb2ee
    as the LLD version must match the LLVM version.
    
    * gnu/packages/llvm.scm (lld-12): New variable.
    * gnu/packages/zig.scm (zig)[inputs]: Change from LLD to LLD-12.
