For alugrid (and c++ libs in general) it will never be too easy to
accomplish this. I think the easiest way is, if the lib contains a 'C'
symbol (could oyu check for the alu-version... how is it stored? as a
symbol? or as some define or enum?). All other symbols will be rather
difficult to check, because they are mangled. In this case you can
check for something like malloc. This will do a "can I find the lib
with this name" test, but not check whether the lib is correct. But
check ,,just'' the linking is already better than nothing.
