Remember that most of the kernel source is about building the kernel,
where we explicitly call the linker directly.

This is about building a user visible object, and we go through the
compiler front end for that.

My only worry is if we were to pick up (eg) libgcc.so* as a dependency,
but that's highly unlikely to go unnoticed if it were to happen, as my
cross-toolchain doesn't have libgcc.so available. ;)

Given that there's gold out there which doesn't work for the VDSO, I
think the solution Nathan has come up with in his reply to your email
is the best resolution to this.
