In theory, yes. In practice libc++.so probably will not be found in the rpath.
It might "just work" to include libcxx's buildlink3.mk from mk.conf.
These are uncharted waters.

Another option is to make a change in the clang package.
Look for these lines in the Makefile and change SunOS to NetBSD.

# Enable full LLVM suite on SunOS
.if ${OPSYS} == "SunOS"

Again, uncharted waters. YMMV.
