Darwin/Mac OS X _init/_fini and _end symbols support

[Pierre d'Herbemont]

Hi!

Here is an other fix for Darwin. There is no __init nor __fini function 
defined on darwin to call all the init and fini functions. You have to 
use some obscure function provided by the system. So here goes the fix 
for winelib :)

Also I did add the fix for the _end symbol you (Alexandre) you 
suggested, that I forgot to submit before.

Thanks,

Pierre

ChangeLog:
Darwin Support for _init/_fini functions and _end symbol.
