Subject: build: keep recursive dependency check stampfiles up to date
X-Git-Tag: v18.06.0-rc1~3864
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=d86802acd8ebe0aaf855dc75ad6276856032bfef;ds=sidebyside

build: keep recursive dependency check stampfiles up to date

Since the main stamp file depends on the _check stampfile, the _check
stampfile needs to be created on the first run as well.

Fixes spurious rebuilds with CONFIG_AUTOREBUILD=y
