That's not actually related to GCC, but the lang/gcc* ports using
the FreeBSD Ports Collection's default that explicitly set


Yes, I know. That's why I said the vendor part must be forced to "unknown".


  CONFIGURE_TARGET?=  ${ARCH}-portbld-${OPSYS:tl}${OSREL}

By default GCC would use the same as clang.


Sure, but that doesn't mean the vendor part of the triple in the default
compiler is guaranteed to be 'unknown'.
