of version 2.8, LLVM is generating slower code than the newer GCCs but generates

...39;unable to compile', or 'compiled

I analysed the dragonegg compile failures. The graphicsmagick,
imagemagick, lame and x264 failures were all failures to link,
due undefined references to builtin_lfoor and/or builtin_lceil.
Recent gcc turns calls to floor/ceil followed by a cast to long
or long long into a call to an lfloor/lceil builtin. These were
not being recognised by dragonegg, so were just being passed on
as is, resulting in the link failures. I just added support for
these builtins and now all of the above...
