Build failure with LLVM/Clang 3.0

Upstream has no problems compiling this with LLVM/Clang, so this needs some attention.

Fix a compilation error with LLVM/Clang 3.1

I should probably have mentioned that I am building boot0 with ZFS support.

With that said, the following patch fixes a compilation error with LLVM/Clang 3.1. Applying the patch and setting BOOT2_UFS=UFS1_ONLY in the environment to remove UFS2 support from stage2 will permit it to build. I had tried BOOT2_UFS=UFS2_ONLY, but the binary was 9 bytes too large.

I am curious how FreeBSD manages to make these things fit.
