For those of you who haven't had the pleasure, here is the breakage:

Undefined symbols:
  "_LLVMInitializeX86Target", referenced from:
      llvm::InitializeAllTargets() in llc.o
  "_LLVMInitializeX86AsmPrinter", referenced from:
      _main in llc.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make[2]: *** [/Volumes/Sandbox/Buildbot/llvm/build.llvm-gcc-i386-darwin9/llvm.obj/Release/bin/llc]
Error 1
make[1]: *** [llc/.makeall] Error 2
make[1]: *** Waiting for unfinished jobs....

Of course, take your time. It's not a problem in the slightest! No
need to worry.
