Package: nvidia-kernel-dkms Version: 390.87-4 Severity: normal Linux 4.19 renamed LDFLAGS to KBUILD_LDFLAGS [1], so use-kbuild-flags.patch doesn't work any more. I can confirm that using KBUILD_LDFLAGS fixes the issue. Do note that older kernels don't set KBUILD_LDFLAGS, so we need to support both for some time.
