Hi,

On FreeBSD 8.2 the binutils version is 2.15 [FreeBSD] 2004-05-23.

Since r129518 and r129571 (when the change was re-introduced after a backout in
r129557) boostrapping llvm/clang on FreeBSD has been broken.

The second stage build dies with:

<plenty more messages like these>
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Can this be fixed in a way that does not require binutils to be upgraded ?
