Arrgh... OK, I see what's going on - export in a lib-y object. For lib/*.c
we deal with that by putting such objects into obj-y; the same certainly
can be done for *.S, but I wonder if a better solution would be to have
lib-y objects scanned for __ksymtab_strings section (grepping in objdump -h
output) and treat the ones that have such as obj-y.
Comments?
