Is that for host or after upgrade? Your build logs had the following:

> _CCVERSION_921dbbb2=FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based on LLVM 6.0.1) Target: x86_64-unknown-freebsd12.0 Thread model: posix InstalledDir: /usr/bin

FreeBSD 11.2/12.0 have Clang 6, FreeBSD 11.3/12.1 have Clang 8.
