Onderwerp: [Buildroot] [PATCHv3 1/2] linux: add option to explicitly specify the kernel image name

For example the upcoming qemu-xtensa patch is using this feature, where the target is called "zImage", but the resulting kernel name
is "Image.elf".

---
Changes v2 -> v3:
  - improve subject (suggested by Thomas P.)
  - LINUX_IMAGE_NAME defaults to LINUX_TARGET_NAME (suggested by Yann)
  - improve help text (suggested by Yann) Changes v1 -> v2:
  - add comment about default value (suggested by Arnout)
  - reorder default value for LINUX_TARGET_NAME (suggested by Arnout)
