[v1,0/3] riscv: make image compression configurable

Message

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'.

Patch 3/3 depends on the previously mentioned patch below.

  riscv: make image compression configurable
  riscv: show help string for riscv-specific targets
  kbuild: buildtar: install riscv compressed images as vmlinuz
