From 1a7bf48eed806beea7e835b31b06aa6bc94da5da Mon Sep 17 00:00:00 2001
From: =?UTF-8?q?Martin=20Storsj=C3=B6?= <martin@martin.st>
Date: Thu, 24 Aug 2017 23:05:21 +0300
Subject: makedef: Extend the script for use with mingw tools as well
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is invoked by setting the NM and AR variables to the names of
those specific tools. The ARCH variable also needs to be provided,
to choose the symbol prefix (nm doesn't provide any option that
dumps the architecture easily).
