$NetBSD: patch-compiler_GHC_SysTools_Process.hs,v 1.1 2025/01/29 13:21:53 pho Exp $

This is more like pkgsrc-specific than an upstream issue. Don't use
"response file", the @FILE syntax while invoking CC or LD. Our tool
wrappers don't look into response files, and therefore can't detect
mistakes like depending on Cabal packages that aren't declared as pkgsrc
dependency.

Note that this patch would break GHC if we didn't have its $ORIGIN use
eliminated because our wrappers hate relative rpaths.
