Ok, as I see, libtool cannot solve this, but as I researched further, libtool 
doesn't need to solve it. Newer GNU 'ld' has the flag --as-needed, which does 
exactly the thing I wanted. The only problem from the libtool side is that if 
I specify LDFLAGS=-Wl,--as-needed, libtool will append these flags after 
dependency_libs, so the option will be useless. I attached a patch which puts 
$compiler_flags before any dependencies. Is this patch acceptable?

Bye,
