Properly set flag_pie and flag_pic
We can't set flag_pie to the default when flag_pic == 0, which may be
set by -fno-pic or -fno-PIC, since the default value of flag_pie is
non-zero when GCC is configured with --enable-default-pie. We need
to initialize flag_pic to -1 so that we can tell if -fpic, -fPIC,
-fno-pic or -fno-PIC is used.
Since Darwin defaults to PIC (__PIC__ == 2) and the PIC setting can't
be changed, skip tests of default __PIC__ and __PIE__ setting for
*-*-darwin* targets.

* opts.c (finish_options): Don't set flag_pie to the default if
-fpic, -fPIC, -fno-pic or -fno-PIC is used. Set flag_pic to 0
if it is -1.
