That's not what I'm seeing here (although I tried with VS2019 and LLVM 9.) 
When using Boost 1.73, and your test program, I get

1>lld-link : error : could not open 
'libboost_serialization-clangw9-mt-gd-x64-1_73.lib': no such file or 
directory

which matches my expectation.

Defining BOOST_LIB_DIAGNOSTIC yields:

1>In file included from testbed2019.cpp:3:
1>In file included from D:\boost_1_73_0\boost/archive/xml_iarchive.hpp:22:
1>In file included from 
D:\boost_1_73_0\boost/archive/detail/auto_link_archive.hpp:45:

file: libboost_serialization-clangw9-mt-gd-x64-1_73.lib [-W#pragma-messages]

Again, as expected, based on the contents of auto_link.hpp.
