#     kbuild: Parameterize kallsyms generation and correct reporting
#     
#     When kallsyms generation happens, temporary vmlinux outputs are linked
#     but the quiet make output didn't report it, giving the impression that
#     the prior command is taking longer than expected.
#     
#     Instead, report the linking step explicitly. While at it, this
#     consolidates the repeated "kallsyms generation step" into a single
#     function and removes the existing copy/pasting.
