Subject: sdk: predefine SOURCE_DATE_EPOCH
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8cc922411561dfa6f65fbb492a7bdb6fb9bbb6d5;p=openwrt%2Fstaging%2Fkaloz.git

sdk: predefine SOURCE_DATE_EPOCH

When building packages within the SDK, there is no Git revision history
available so prepopulate SOURCE_DATE_EPOCH in version.mk, similar to
how we handle REVISION already.
