By "new", do you mean ld 2.14? "binutils" and "gcc" are distributed by
separate entities, so there's no exact correspondence.

The real problem is, the binutils package may well be older than the
one in the tree, or if not that, exactly the same, and it's annoying
when pkgsrc install multiple versions of the same program.

Look in "lang/gcc3-c/Makefile.common" at the addition of
--with-as=fullpath, conditionally on ${USE_BINUTILS} being set. If
we're pulling in binutils anyhow, we might as hardcode the path to
"ld", too, with --with-ld. We should probably just switch the test
from "${AS}" to "{LD}, and bump the version tested for to 2.14.
