Subject: kernel: set --build-id to none
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=813b05a8db9ca8612b4fd2b1bb18769e37e08201;p=openwrt%2Fstaging%2Faparcar.git

kernel: set --build-id to none

The Build ID is meant to help distinguish between build environments. In
our case it makes it very harder to reproduce binaries we offer to
download.

Set the Build ID to `none` and drop it from the resulting vmlinux.
