ld was still in use last I checked. I've been using LOCAL_ITOOLS
to avoid the problem for powerpc64's world32 activity where the
problem was happening for me.
See Ed Maste's -r320502 check in which I expect is a alternate
workaround for the lack of "head" in that I get the same message
that is being avoided unless I cause "head" to be in the ITOOLS:

Log:
bsd.linker.mk: add band-aid for linker invocation failure
=20
In some cases bsd.linker.mk reports an error like:
=20
make[4]: ".../share/mk/bsd.linker.mk" line 56:
Unknown linker from LD=3Dld -m elf32ppc_fbsd:"
=20
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.
=20
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.

The actual error is from the piping through head
when head is missing, at least in my context.
