Subject: target.mk: check that CPU_TYPE has known CPU_CFLAGS mapping
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c8a0f3aa290c7f64dbfe5337537defe660952c0c;p=openwrt%2Fstaging%2Fhauke.git

target.mk: check that CPU_TYPE has known CPU_CFLAGS mapping

If someone creates a target and indicates a CPU_TYPE, but there's
no corresponding support for that CPU_TYPE's flags in include/target.mk
then that should probably be indicated rather than silently ignored.
