I should have noted someplace that the correct binding for the context
is for Lex/Lexer.cpp to find:
/usr/src/contrib/llvm/tools/clang/lib/Headers/altivec.h
and not one of the FreeBSD headers. (Very different content.)

So:
/usr/src/contrib/llvm/tools/clang/lib/Headers
is missing and is where altivec.h should be found for
the include in Lex/Lexer.cpp .
It is too bad that the altivec.h naming matches between
clang-internal headers and FreeBSD headers, making
correct selection messier to deal with.
The code in Lx/Lexer.cpp looks like:
#ifdef __SSE2__
#include <emmintrin.h>
#elif __ALTIVEC__
#include <altivec.h>
#undef bool
#endif
