--- Comment #3 from Anatol <anatol.pomozov at gmail dot com> --- I just hit this issue when tried to build cross-tools for arm64. CFLAGS_FOR_TARGET works as expected and I was assuming that CXXFLAGS_FOR_TARGET is used instead of CXXFLAGS. If CXXFLAGS_FOR_TARGET is not honored now, what is recommended workaround for cross-compilers that need different CXXFLAGS for host and target?
