How to build ECL from sources to be able to debug itself?

Hi, I need to debug a possible socket bug on android; I've set up everything to be able to use a gdbserver on it, but it doesn't show anything useful (only a disassembly, which is cryptic to me). Is there a simple way to build all of prebuilt ECL (including sockets etc.) in debug mode? I already tried the configure options which mention debug, but this didn't change anything. Thanks, Paul
