In some build experiments for amd64 -> aarch64 cross
builds/local-file-system-installs for stable/11
-r322591 with WITH_LLD_IS_LD=3D I got examples of
delete-old delete-old-libs deleting the path to ld
after a from-scratch build:
>>> Removing old files (only deletes safe to delete libs)
=
/usr/obj/DESTDIRs/clang-cortexA53-installworld-dist-from-src/usr/share/man=
/man4/hv_vss.4.gz
/usr/obj/DESTDIRs/clang-cortexA53-installworld-dist-from-src/usr/bin/ld
>>> Old files removed
>>> Removing old directories
=
/usr/obj/DESTDIRs/clang-cortexA53-installworld-dist-from-src/usr/lib/debug=
/usr/lib/private
>>> Old directories removed
To remove old libraries run 'make delete-old-libs'.
>>> Removing old libraries
Please be sure no application still uses those libraries, else you
can not start such an application. Consult UPDATING for more
information regarding how to cope with the removal/revision bump
of a specific library.
>>> Old libraries removed

So no hard or symbolic link pointing to ld.lld .
