[LEDE-DEV] "someone does not honour COPTS correctly" - Makefile issue?

[Sebastian Kemper]

Hi all,

I'm working on a package for OpenWRT/LEDE. A pull request with the
Makefile is here: https://github.com/openwrt/telephony/pull/124/files

During compilation I see a lot of these warnings:

cc1: note: someone does not honour COPTS correctly, passed 4 times

Are these caused by my Makefile or by the FreeSWITCH source? If caused
by the Makefile, how can I fix them?

Thanks!
Sebastian
