I've done this before. I think it is your TNGLDFLAGS, which should be
-ltng_io based on what was in plugins/Make-arch for LINUX or LINUXALPHA.
I don't think it is set in LINUXAMD64 by default, but -shared isn't
going to cut it. If my hypothesis is correct, your linkage should fail
with alot of calls to the tng library itself.
