Creating Add build information into a Yocto image
Importing variables into the device with buildinfo
There is a little known image feature in Yocto called buildinfo that will help us get the required information.
Buildinfo is available in Yocto 1.8 and later versions. This image feature will write a set of OpenEmbedded variables to a file /etc/build in the image, which in turn gets written to the target device.
To enable buildinfo, open conf/local.conf and append
INHERIT += "image-buildinfo" IMAGE_BUILDINFO_VARS:append = " DATETIME DISTRO_NAME IMAGE_BASENAME MACHINE TUNE_PKGARCH" IMAGE_BUILDINFO_VARS:append = " MACHINE_FEATURES DISTRO_FEATURES COMMON_FEATURES IMAGE_FEATURES" IMAGE_BUILDINFO_VARS:append = " TUNE_FEATURES TARGET_FPU"
Then build the desired image, e.g. with bitbake -k core-image-minimal. And run the image, e.g. with runqemu qemuarm nographic, and look at the file generated in /etc/build.
A sample resulting /etc/build file is shown below.

Buildhistory
To enable buildhistory, open conf/local.conf and append
INHERIT += "buildhistory" BUILDHISTORY_COMMIT = "1"
The same details are registered on the HOST for every build when you enable buildhistory
