When building the patched version of the kernel, vmlinux has to be
linked with the '--warn-unresolved-symbols' linker flag. Otherwise the
link will fail if the patch uses kpatch-specific symbols like
kpatch_shadow_alloc() and friends.
As of upstream Linux commit b36fad65d61f ("kbuild: Initialize exported
variables"), LDFLAGS_vmlinux= no longer works from the command line,
resulting in '--warn-unresolved-symbols' no longer getting set.
Instead we can use kpatch-gcc to pass the flag to the linker.
Fixes #627.
