From 2c2a92573598ddbc33c023fe5d499191491fb523 Mon Sep 17 00:00:00 2001
From: Richard Purdie <richard.purdie@linuxfoundation.org>

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

Pass CXXFLAGS_FOR_BUILD in a couple of places to avoid these errors.

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]
