For now I have two facts:

1. Our Jenkins server has no home folder for build user, and I have the 
following error message:

NOTE: Running task 46 of 424 
(multiconfig:rpi-jessie:/workspace/git/isar_asmirnov_devel/meta/recipes-core/isar-bootstrap/isar-bootstrap.bb:do_generate_keyring)

Log data follows:

failed with exit code '1'

So the default HOMEDIR is /root and it tries to create something in it.

2. After building on my local machine, timestamp of files in ~/.gnugpg 
folder are updated.

I could be wrong, but with --homedir, the second problem was gone.
