build: Separate out prebuilt kernel logic from toplevel Arch-specific stuff shouldn't be in the toplevel Makefile, forthcoming patches will soon introduce special interrupt handling logic for other arches.

x86: convert gen_idt to Python This is one less host tool we have to compile for every build, and makes the build tools more portable across host OSes. The code is also much simpler to maintain. Issue: ZEP-2063 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

$(call cmd,gen_idt)
build: simplfy how extra build steps are specified For various reasons its often necessary to generate certain complex data structures at build-time by separate tools outside of the C compiler. Data is populated to these tools by way of special binary sections not intended to be included in the final binary. We currently do this to generate interrupt tables, forthcoming work will also use this to generate MMU page tables. The way we have been doing this is to generatea "kernel_prebuilt.elf", extract the metadata sections with objcopy, run the tool, and then re-link the kernel with the extra data *and* use objcopy to pull out the unwanted sections. This doesn't scale well if multiple post-build steps are needed. Now this is much simpler; in any Makefile, a special GENERATED_KERNEL_OBJECT_FILES variable may be appended to containing the filenames to the generated object files, which will be generated by Make in the usual fashion. Instead of using objcopy to pull out, we now create a linker-pass2.cmd which additionally defines LINKER_PASS2. The source linker script can #ifdef around this to use the special /DISCARD/ section target to not include metadata sections in the final binary. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
