Yes, the simplest way to reproduce the problem is to run

mkdir build
cd build
cmake ..\llvm -G Ninja  -DCMAKE_CXX_CREATE_STATIC_LIBRARY=foobar
-DCMAKE_LINKER=c:\users\espindola\llvm\inst\bin\lld-link2

and then

ninja -v lib\LLVMSupport.lib

I would expect it to fail trying to run foobar, but it works by
running lld-link2
