shows a way of finding out any libraries that executables link to, where
there are no references to what's in the library.
ECL would appear to have 3 in the current version of Sage, though it is
reduced to 2 in the latest {{{git}}} snapshot of ECL I downloaded
yesterday:
{{{

}}}
Note there are two unused libraries:
{{{
unused object=/lib/libsocket.so.1
unused object=/lib/libintl.so.1
}}}
ECL should only link to these libraries if it needs them, which I expect
it does with some options. There were no options given to configure here.
