RuntimeLoader now works on Mac OS X

[Andre Pang]

Thanks to the amazing work by Wolfgang Thaller on GHC for Mac OS
X, it was trivial to port the RuntimeLoader to work on Mac OS
X (or Darwin, if you want to be pedantic).  

The runtime loader enables a GHC program to load object files
(.o) at runtime and load functions in them, much like how you can
dlopen() a shared library on many Unixes.

For more information on the runtime loader, see

It's been tested and verified with GHC 5.04.2 on Mac OS X, and
GHC 5.04 on Linux.  If it works on Windows (and there's a good
chance it might), please let me know!
