<pre>When passed --target=powerpc64-unknown-freebsd, clang creates ELFv1 binaries,
even on a ELFv2 system. ELFv2 binaries are created only when the version is
appended, like --target=powerpc64-unknown-freebsd13.0.
Since ELFv1 is generally considered legacy on FreeBSD and on life support, it's
fine to just default to ELFv2. Clang never worked properly on FreeBSD on ELFv1
anyway.
The following patch fixes this issue.
