So this config was generated by older version of libtool. AFAIK format
of this config didn't change, so it's not important which litool version 
generated it.

This was manual change of libdir= to create small test-case. I usually have
this file as /usr/lib/libdb-3.1.la and:
installed=yes
libdir='/usr/lib'

Yup. IMO it shouldn't use shared lib but libtool puts .//libdb-3.1.so
at gcc command line. Why? old_library='' so there is no static library.

It's obvious. Whole problem is here:
# /bin/sh libtool --mode=link gcc  -o test -s -all-static test.o ./libdb-3.1.la
(Note that there is old_library='' in libdb-3.1.la; no static library)
gcc -o test -s -static test.o  .//libdb-3.1.so -Wl,--rpath -Wl,./ -Wl,--rpath 
-Wl,./
... libtool calls gcc with ,,./libdb-3.1.so'' (as it should do but for
_static_ library only) so for me it's libtool bug.

gcc -o test -s -static test.o  .//libdb-3.1.so
won't work and it's ok.
