min-dl: minimal dynamic linker implementation
To support dynamic linking, each ELF shared libary and each executable that uses shared libraries has a Procedure Linkage Table (PLT), which adds a level of indirection for function calls analogous to that provided by the GOT for data. The PLT also permits "lazy evaluation", that is, not resolving procedure addresses until they are called for the first time.
Since the PLT tends to have a lot more entries than the GOT, and most of the routines will never be called in any given program, that can both speed startup and save considerable time overall.
min-dl introduces a straightforward way to load the specified shared objects and then perform the necessary relocations, including the shared objects that the target shared object uses.
