So I thought, but it doesn't:

 $ LDFLAGS=-liberty LIBS=-liberty make
[...]
/bin/bash ../libtool --silent --mode=link --tag=CXX g++  -Wnon-virtual-dtor 
-Wno-long-long -Wundef -Wall -W -Wpointer-arith -Wwrite-strings -O2

So the question is really, `How do I trick libtool into adding an -l
option that I know I need, when libtool doesn't believe me?'
