  If you don't want to clobber your buildroot tree with
configs/mysystem_dev_defconfig, you can instead do:

  make clean
  cat mysystem_base_defconfig.frag mysystem_dev_defconfig.frag > /tmp/mysystem_dev_defconfig
  make defconfig BR2_DEFCONFIG=/tmp/mysystem_dev_defconfig
  make


  And to create the _dev fragment, you can try something like:

make savedefconfig
sort defconfig mysystem_base_defconfig.frag | uniq -u > mysystem_dev_defconfig.frag

(this is just from the top of my head so YMMV).
