sample to static link a compiled dynamic library into a compiled binary

[lunixbochs]

1. combine segments (not by extending binary's existing segments, but by adding new ones)
2. change relocation offsets for the library and add its relocations to the binary's relo table
3. add all library symbols to binary relo table
4. don't think I need to preemptively do relocations for any symbols from the library, as long as ld.so considers the binary's own symtab when loading
5. add all library symbols to symtab
6. merge library dependencies
7. re-emit combined binary!
8. repeat as necessary

9. update .init, .fini / ctors/dtors
