$NetBSD: patch-compiler_GHC_SysTools_Process.hs,v 1.1 2023/01/21 04:49:25 pho Exp $

This is more like pkgsrc-specific than an upstream issue. Unless we
are on Windows, 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.
