Compiling on MacOSX 10.6 and 64bit *kernel*

[Hendrik Visage]

Okay, the erlang R13B2 compile to 64bit *user*code*, but currently
only while running a 32bit *KERNEL* :(

I've made a "distro" patch on http://gist.github.com/232115 that only
touch the two configure scripts, not the configure.in (call me lazy ;)
to be able to compile otp R13B2 on MacOSX running 64bit kernel.
