MINOR: compat: detect support for dl_iterate_phdr()
We'll use this glibc function to dump loaded libs. It's been
available since glibc-2.2.4, and as it requires dlpi headers defined
in link.h, it implicitly relies on dlfcn, thus we condition it to
USE_DL. Other operating systems or libc might have different
dependencies so let's stick to the bare minimum for now.
