The test in that commit `RUN: lld-link %t.entry.obj /libpath:%t-libdir %t.ldcfg-defaultlib.lib /out:%t.exe /entry:entry /subsystem:console /dependentloadflag:0x801 2>&1 | FileCheck %s --allow-empty --check-prefix NO-WARN` does not have `/nodefaultlib`, would that not pull in the default CRT libs and invalidate the test?
