* ltmain.in: extract symbols from program objects to nlist first,
then translate them to the export_symbols format. Now it works,
but it appears to be needlessly extracting the symbol list from
dlpreopened libraries twice
* ltmain.in: temporarily disable dlopen_self when linking with
-static or -all-static, until we figure out how to test whether it
works at configure time
* TODO: remember to fix this later
* tests/build-relink.test: when hell is expected to fail, run it
