Implement ifunc support for static executables.

A static executable is almost entirely statically relocated by the
linker, with the exception of IRELATIVE relocations, which must be
resolved by libc by enumerating the relocations using the special
linker-defined symbols __rela?_iplt_{start,end}. This patch implements
ifunc support by enumerating the relocations in this way.
