Commit e73177ea5fd611026abcbaecc6232eee8d8d2ed8 by kevin.petit
Fix use of add_llvm_tool in projects that build no targets
Projects that set LLVM_TARGETS_TO_BUILD to an empty list can't use
add_llvm_tool (and probably other macros).
Here's the error that this change fixes:
list sub-command REMOVE_ITEM requires two or more arguments.
