maintainer-feedback:
Bug 240434: emulators/virtualbox-ose-kmod: fix "make -s" build
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240434



--- Description ---
${ECHO} is a make(1) builtin which is empty when "-s" is used.	For functional
build modifications ${ECHO_CMD} must be used, because the build fails
otherwise.
