Auto merge of #2962 - alexcrichton:demote-error, r=brson

Demote duplicate build target error to a warning

Added in #2847 this ended up unfortunately breaking the `regex` crate on
nightly, so let's just issue a warning for awhile first. Eventually we can
promote this to an error if it becomes a problem.
