This is actually a somewhat crucial step as it cleans out any old artifacts to make sure we don't preserve anything by accident. Could the *.o files above be generated into something like build/$target/rtstartup/foo.o and then copied from there to the sysroot?

Ok, it looks like all the remaining sysroot components are already built somewhere else and then copied to sysroot directory.

Fix test caching on Windows/GNU Addresses rust-lang#36385 (comment) Previously the sysroot directory was purged on every build and mingw startup objects were rebuilt unconditionally and always triggered test reruns. Now the sysroot directory is reused and mingw startup objects are rebuilt only when necessary, so test caching works.
