Invoking `guix environment guix`, I found this collision alarming. Do
you think it's a problem?

I ran `guix pull` yesterday or the day before. Is there a way to
determine the git commit that corresponds with this version of Guix?

I added the line breaks.

This collision is expected.  The 'ld' within ld-wrapper, generated from
the template in gnu/packages/ld-wrapper.in, automatically adds -rpath
arguments to the linker for each shared library, so that the runtime
linker will be able to find them in their non-standard locations.

If one of those 'ld' files is the real ld, and the other is supposed to be
a wrapper around the real one that adds functionality, then how is it that
things will always work out OK if only one of them is installed? I'm not
sure how the "arbitrary" selection works, but doesn't the choice matter?

The choice matters, indeed, but it’s deterministic: the first one wins.
And in this case, the first one is the wrapper.

Now, it might be best for ‘guix environment’ to silence these warnings.
