Building binutils on a clang profile, which uses `llvm-ar` as the archiver, fails during the initial tests.

It builds fine with gcc, or if pgo USE flag is disabled. 

```
checking for -plugin option... checking for x86_64-pc-linux-gnu-ar... (cached) llvm-ar
no
configure: error: AR with --plugin and rc is required for LTO build
```

Full build log provided in file.

Using -stdlib=libstdc++ on Clang profiles is not considered supported. It'd be far better to start with a "normal" stage3 & profile, then set CC etc, because those profiles assume libcxx in various places.

And the stages will be ABI incompatible anyway.

Also, the symlink is dead: !/var/db/repos/gentoo/profiles/default/linux/amd64/17.1/clang.
