   1 kernel: use LDFLAGS when linking modules
   2
   3 Currently, linking module objects is simply using $(LD), assuming that
   4 the default emulation is correct for the current architecture.
   5
   6 However, that might not be the case when the toolchain default is not
   7 the same as the current arch. For example, if the toolchain defaults to
   8 i386 and is capable of x86_64, and we're targetting x86_64 (or the
   9 opposite), the link would fail because the ld emulation is incorrect:
  10
  11     .../i686-pc-linux-gnu-ld: Relocatable linking with relocations from
  12     format elf64-x86-64 (.../nvidia-driver-370.23/kernel/nvidia/nv-frontend.o)
  13     to format elf32-i386 (.../nvidia-driver-370.23/kernel/nvidia/nv-interface.o)
  14     is not supported
  15
  16 Add use of $(LDFLAGS) when doing the link, as the kernel provides the
  17 proper emulation in those.
