I've just removed them and it worked. Or is there a reason for rpath to
system lib directory?

What about other keys? I've also encountered -fwhole-program and

What I plan to do is:

USES+=	compiler:env

.include <bsd.port.pre.mk>

.if ${COMPILER_TYPE} == "clang"
	@${REINPLACE_CMD} -e 's|-fwhole-program||' ${WRKSRC}/CMakeLists.txt

but what if next version of clang learns of this key? I'd like to have
something like

.if ! ${COMPILER_SUPPORTED_ARGUMENTS:M-fwhole-program}
	@${REINPLACE_CMD} -e 's|-fwhole-program||' ${WRKSRC}/CMakeLists.txt

CXXFLAGS+=	-malign-double
