From 7f40f8321fb999e9b34d948724517d3fb0d26820 Mon Sep 17 00:00:00 2001
From: Richard Purdie <richard.purdie@linuxfoundation.org>
Date: Thu, 28 Oct 2021 11:33:40 +0100
Subject: [PATCH] Pass CXXFLAGS_FOR_BUILD in a couple of places to avoid these
 errors.

If CXXFLAGS contains something unsupported by the build CXX, we see build failures (e.g. using -fmacro-prefix-map for the target).

2021-10-28 Richard Purdie <richard.purdie@linuxfoundation.org>

ChangeLog:

    * Makefile.in: Regenerate.
    * Makefile.tpl: Add missing CXXFLAGS_FOR_BUILD overrides

Upstream-Status: Pending [should be submittable]
