make xdev broken

[Warner Losh]

In 9.2 stable on amd64, make xdev is broken.

sudo make xdev XDEV=i386 XDEV_ARCH=i386

terminates with

In file included from /imp/svn/stable/9/lib/clang/libclanganalysis/../../../contrib/llvm/tools/clang/lib/Analysis/CFG.cpp:17:
/imp/svn/stable/9/lib/clang/libclanganalysis/../../../contrib/llvm/tools/clang/include/clang/AST/Attr.h: In static member function 'static bool clang::MSInheritanceAttr::classof(const clang::Attr*)':
/imp/svn/stable/9/lib/clang/libclanganalysis/../../../contrib/llvm/tools/clang/include/clang/AST/Attr.h:148: error: 'LAST_MS_INHERITABLE' is not a member of 'clang::attr'

what's up with that? Any ideas on how to fix this?
