I foung the same.  The only way I managed to get it to work was to
ignore configure and use cmake.  So, in another directory use "ccmake
<path-to-llvm-source>" (where ccmake is one of the frontends to cmake)
and turn on the CMAKE_BUILD_EXAMPLES option (and set
CMAKE_INSTALL_PREFIX if you want) then use make in that directory.
"make install" will also work.

On the downside, I haven't worked out how to produce API documentation,
whereas I could with the in-tree build.
