[make-initrd] [PATCH v6 13/22] bootchain-core: introduces new parameter bc_test

["Leonid Krivoshein" <klark.devel@gmail.com>]

Enabling the bc_test option allows the boot log to be saved to the stage2
even when extended debugging has not been enabled. It will be possible to
examine the contents of the boot log without additional debugging messages.
