treewide: remove -ldl linker flags

Browse source 
With all libcs I'm aware of, libdl is now either empty (Glibc, musl,
uclibc, illumos), a symlink to libc or equivalent (Apple), or does not
exist (FreeBSD, NetBSD).  So explicitly linking libdl now does nothing
for the former platforms, and breaks the build for the latter
platforms.

With this patch I've removed -ldl from all overridden linker flags for
all free packages in Nixpkgs.  Everything still seems to build.
