Because the linker can't put branch stubs within object code sections,
so when you incrementally link them too large, the linker can't resolve

They may know something about the reason of failure.

Instead of linking all compilation units again each time vmlinux_link is
called, reuse vmlinux.o from modpost_link.
With x86_64 allyesconfig, vmlinux_link is called three times and reusing
vmlinux.o reduces the build time ~38 seconds on my system (59% reduction
in the time spent in vmlinux_link).
