Seems like -Z prefer-dynamic causes this.

[alexcrichton]

What linux OS is this running on? This looks like a dupe of #10743 to me

[klutzy]

@alexcrichton I got the result on debian x64. I thought it is similar to #2510 since -Z print-link-args -Z prefer-dynamics doesn't show -lm.

[alexcrichton]

In that case, this is definitely a dupe of #10743, closing in favor of that one.
