Is there some magic that should be included here (or should've been included with the cherry-picked bits) to force a bootstrap LLD to be built?

I hadn't upgraded my host yet with the cherry-picked commits from this morning and thus had to force WITHOUT_SYSTEM_LINKER for the VFP flag bits. The build hasn't finished running, so I can't say conclusively that that was the only problem, but it certainly wouldn't have helped. =)

On commit when we bump the FreeBSD version number reported in ld.lld -v it should DTRT, but for testing I just did a rm -rf of the arm.armv7 obj tree.
