this ld/ld.lld selection feels very odd. Ideally we just stick with one `ld`.
If a user prefers `ld.lld`, customize this preference in Clang configuration
file.
The shared C++ code trying to appease some sets of users could easily end up
with something with unprecdictable behavior, which offers worse user experience
for the other set of users.
