[Buildroot] [PATCH 2/7] package/linux: don't enforce check for DTS when not building

[Yann E. MORIN]

Currently, this is triggering the error message:
    make randconfig
    make source

Limit the checks that enforce a DTS is set and at most one DTB is
appended to when we are actually building, like is done for the
configuration-file variables.
