I've fixed log2()/exp2() for now. The dependency on trunc() will 
go away, once I add ARM assembler versions for floor/ceil/trunc 
(the soft-float functions in libc are incredibly slow).

I'm not sure what exactly you're doing there, but you should know
the generated *.h files are highly dependent on the target
architecture, the toolchain and the Makefile flags. That's why
they are dynamically generated at build time! Never copy them
around or use them outside of the source tree.

The install docs clearly state:

  It's strongly suggested to build LuaJIT separately using the
  supplied build system. Please do NOT attempt to integrate the
  individual source files into your build tree. You'll most likely
  get the internal build dependencies wrong or mess up the
  compiler flags. Treat LuaJIT like any other external library and
  link your application with either the dynamic or static library,
  depending on your needs.

Oh dear ... ok, I'll add this.
