1425906 - Windows linkers interpret LINK specially, so we can't `export LINK`

Status: RESOLVED FIXED

(Firefox Build System :: General, enhancement)

Description

[(Away)]

link.exe interprets getenv("LINK") as a set of options to prepend to its command line: https://msdn.microsoft.com/en-us/library/6y6t9esh.aspx

And lld-link mimics this behavior: https://github.com/llvm-mirror/lld/blob/master/COFF/DriverUtils.cpp#L753

So bad things happen if we try to `export LINK=...` on Windows. We'll need some other way to tell the build system to use lld.
