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