In theory ldd is a subset of readelf, so we've already got most of the code. In practice, the OTHER thing it does is try to dlopen() each library so it can get a path and address out of /proc/self/maps.
The problem is if you're statically linked, bionic links in a dlopen() stub return ing NULL. Which makes sense because you couldn't USE the dlopen() result because of the old "now we have two heap pointers and if you malloc() from the dynamic one and free() into the static one and you've cross-linked your heaps" problem, but all I'm trying to do is get the path to the file and the preferred load address. Not entirely sure the right thing to do here. This is one of those "almost entirely trivial, except for the land mine" things. I guess I can just print the library name from the ELF info but not the => part when dlopen() returns null?
