kbuild: link of vmlinux moved to a script
Move the final link of vmlinux to a script to improve readability and maintainability of the code. The Makefile fragments used to link vmlinux has over the years seen far too many changes and the logic had become hard to follow. As the process by nature is serialized there was nothing gained including this in the Makefile. "um" has special link requirments - and the only way to handle this was to hard-code the linking of "um" in the script. This was better than trying to modularize it only for the benefit of "um" anyway. The shell script has been improved after input from: Arnaud Lacombe <lacombar@gmail.com> Nick Bowler <nbowler@elliptictech.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Arnaud Lacombe <lacombar@gmail.com> Cc: Nick Bowler <nbowler@elliptictech.com> Cc: Richard Weinberger <richard@nod.at> Signed-off-by: Michal Marek <mmarek@suse.cz>
