BTW, I'd always write this as
NVCC = nvcc
SUFFIXES = .cu
.cu.$(OBJEXT):
$(NVCC) -c -o $@ $<
so that your user can override nvcc with her nvcc-3.x or $host-nvcc if
need be (or you can go all the way and add an AC_CHECK_TOOLS([nvcc])
to configure.ac).

automake doesn't know which linker to use with .cu files. So, if you
happen to not use any other language in this Makefile.am file, then
$(LINK) will probably not be defined at all. You could either define
it to something sensible (containing $(NVCC) if that is appropriate)
or, if you just want to use the C linker, add a line
EXTRA_first_SOURCES = dummy.c
(see 'info Automake "how the linker is chosen"').
BTW, the automake@ list is a bit more appropriate for such questions
(you are likely to get an answer about Automake more quickly).
Cheers,
Ralf
