Preloader Compiles with Coverage Flags

[Aaron Arvey]

This is handy for when you want to compile entire wine source with
gcov coverage analysis enabled.

See http://www.winehq.org/hypermail/wine-patches/2005/02/0000.html
for more information on how to compile wine with gcov support.

Changelog:
    * loader/preloader.c
      adds empty __bb_init_func function
