Cody Tapscott 4113a790b0 CMake: Search more permissively for LLD
This change relaxes the restriction added in the prior commit that LLD
should be alongside LLVM.

This also leaves unresolved the issue of making sure the link mode
(static or shared) of LLD matches that of LLVM/Clang. That would be an
unfortunate restriction, since LLD seems to be provided only as a static
lib on some distros.
