Log:
  MFC r366981:
  
  Only use ASAN when using the in-tree compiler
  
  When building FreeBSD 11 on a FreeBSD 12 system with
  CROSS_TOOLCHAIN=llvm10 we end up trying to link against the packaged
  version of the sanitizer library.  This resulted in a requirement for
  getentropy(3) which is not present in FreeBSD 11.
