Subject: build: add HOST_CXXFLAGS for host build
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=87d489f67a35968242cd4f192dc363dc87056844;p=openwrt%2Fstaging%2Fnbd.git

build: add HOST_CXXFLAGS for host build

Added HOST_CXXFLAGS to specify CXXFLAGS during host-compile
(e.g. to specify c++ standard: HOST_CXXFLAGS += -std=c++11)
