FreeBSD use of undeclared identifier 'CLOCK_MONOTONIC_RAW'

Compilation fails with the following:
mariadb/mariadb_connection.c:655:27: error: use of undeclared identifier 'CLOCK_MONOTONIC_RAW'
clock_gettime(CLOCK_MONOTONIC_RAW, &self->last_used);

A google search found the same error in a similar environment in a completely different project:
https://github.com/basil00/reqrypt/issues/20

The solution there was to add the following:
#ifndef CLOCK_MONOTONIC_RAW
#define CLOCK_MONOTONIC_RAW CLOCK_MONOTONIC
#endif
