lang/rust: Attempt to address unreliable rust-lld build
It sometimes fails [0,1] and sometimes succeeds [2,3]. When it
fails it fails with

CMake Error at CMakeLists.txt:23 (message):
llvm-config failed with status No such file or directory
-- Configuring incomplete, errors occurred!
There seems to be some kind of race when using llvm-config-wrapper,
but at the point where LLD is built, both llvm-config and
llvm-config-wrapper should definitely be available. Both are built
successfully much earlier in the build. Attempt to improve reliability
by not using the wrapper. It is a hack in the first place that is
only really needed on Windows.
This is a shot in the dark. I am unable to reproduce this myself.
