  Changed paths:
    M clang/test/Driver/baremetal.cpp

  Log Message:
  -----------
  [Driver][test] Add -no-canonical-prefixes after D154357

If the path components of %clang contain a symlink, e.g.

```
% cd /tmp; ln -s Rel xxx
% /tmp/xxx/bin/clang --target=powerpc-unknown-eabi -xc /dev/null '-###'
InstalledDir: /tmp/xxx/bin
...
"-internal-isystem" "/tmp/Rel/bin/../lib/clang-runtimes/powerpc-unknown-eabi/include"
```

the test will fail. Such commands should use -no-canonical-prefixes, or
derive the include and library paths from cc1 -isysroot using driver
--sysroot.
