Error out on attempt to link amd64 kernel with old binutils linker

As of r333461 we require ifunc support to link a working amd64 kernel.
The default in-tree bootstrap linker is lld and it has the required
support, as does any modern out-of-tree binutils linker. The in-tree
GNU ld is from binutils 2.17.50 and it does not have ifunc support,
so produce an error rather than a broken kernel.

Also switch the logic to enable this for any non-lld linker, since
filter library support is fairly simple and is very likely supported
by any other linker capable of linking the FreeBSD base system.

Provide libdl.

Create libdl.so.1 as a filter for libc.so.7 which exports public dl*
functions. The functions are resolved from the rtld instead, the goal
of creating library is to avoid errors from the static linker due to
missed libdl. For static binaries, an empty .o is compiled into
libdl.a so that static binaries still get dl stubs from libc.a.

Right now lld cannot create filter objects, disable libdl on arm64
when binutils are not used.

bsd.linker.mk: add band-aid for linker invocation failure

bsd.linker.mk: add band-aid for linker invocation failure

In some cases bsd.linker.mk reports an error like:

make[4]: ".../share/mk/bsd.linker.mk" line 56:
Unknown linker from LD=ld -m elf32ppc_fbsd:"

For now change this to a .warning, and then assume GNU ld 2.17.50.
At present the linker type detection is used only for enabling build-id,
and we can carry on without it when type detection fails.

Also, show errors from ${LD} --version to aid in failure diagnosis.
Successful invocations of ${LD} --version produce no output on stderr
so this will not create any spam in non-failing builds.
