a) LLVM could be built  just for one target(LLVM_TARGETS_TO_BUILD)
b) With LTO this case might happen more often, where an user would have 
compiled LLVM just for one architecture and lld would support other 
architectures that LLVM would not support.
c) Printing all the targets/flavors that the linker currently supports.

Yes, right.
