[PATCH v2 0/2] riscv: make image compression configurable

[Emil Renner Berthing]

Masahiro's patch[1] made me wonder why we're not just using KBUILD_IMAGE
to determine which (possibly compressed) kernel image to use in 'make
tar-pkg' like other architectures do. It turns out we're always setting
KBUILD_IMAGE to the uncompressed Image file and then compressing it into
the Image.gz file afterwards.

This series fixes that so the compression method is configurable and
KBUILD_IMAGE is set to the chosen (possibly uncompressed) kernel image
which is then used by targets like 'make install' and 'make bindeb-pkg' and
'make tar-pkg'.

Changes in v2:
- Rebase on riscv/for-next
- Use boot-image-$(CONFIG_..) := assignments rather than ifeq train in
  patch 1
- Drop patch 3 already applied to kbuild/for-next
