Hello Sam,

What macro should set for linker parameters of foo.o ? I'm not shure.
Have you read:
Yes. This was a *very* helpfull. And many examples spokes about LDFLAGS_$@ there. Not directly described for modules.

Took a deeper look.
I saw one reference to LDFLAGS_$@ that is wrong:
LDFLAGS Generic $(LD) options

Flags used for all invocations of the linker.
Often specifying the emulation is sufficient.

LDFLAGS := -m elf_s390
Note: EXTRA_LDFLAGS and LDFLAGS_$@ can be used to further customise
the flags used. See chapter 7.

The chapter reference is also bad...
The other references to the LDFLAGS_$@ are in other situations - it is
used in several places.

If your example requires the LDFALGS_$@ I wil introduce it - for now
it has not been required (except for vdso support where it was hacked).

I will check EXTRA_LDFLAGS compatibilities with older kernel versions. Than I come back with results. Currently I no need LDFLAGS_$@.
