I don’t think so.  I only added this to work around the bug.

By default it does the right thing and embeds the full path to “which”
(at configure time) in the library.  Since the binaries are now
uncompressed, the references are visible to Guix, so we should keep the
reference instead of just a dangling pointer to “which”, in my opinion.

Okay!
