I see this issue is not yet fixed in:

Hi sab,

Hmm. Looking at TPR#20337 which is the report Chris filed, this was fixed in the 14.9 release. Though I just checked and see the warning. We must have accidentally reintroduced this at some point. I’ve reopended the report and will have out engineers take a look.

Note that “-fPIC” is a no-op on MacOSX and the fix is for the compiler to ignore this flag.

This issue should be resolved in 19.1
