payloads/external/LinuxBoot: Clean up
There were some issues with the current Linuxboot Makefiles.
- multithreaded compilation didn't work, because some prerequisites
were missing
- initramfs wasn't added for x86 qemu boot.
- riscv support was incomplete
It began with separate patches, but resulted in a clean up patch, that
is hard to separate. The most important changes are the following:
- Instead of phony targets, actual files are now used as prerequisites
- riscv can now be used as target
- initramfs works now also for x86
- instead of querying the most recent version from the internet, I set a
known working version (because I tested it) that can be customized
and/or upgraded in the future. The reasons:
- querying the version from the internet requires a constant
connection to the internet even after linux kernel is already
build (aka subsequent builds).
- one usually wants to use a known working version, but optionally
still have the posibillity to choose a custom one. This patch
introduces this possibility in its most simple form.
- I removed as much ifeq statements as possible and moved that
responsibility to Kconfig, because they tend to make the
Makefile less readable.
