patch: Update of pep x86_64 support of ld

Hi,

I recognized some troubles in the pe+ support for x86_64 mingw target. It 
warns about '@xx' stuff passed by gcc, but this can be silently ignored by 
setting 'pep_enable_stdcall_fixup' to true for now. In near future when I 
fix spec definition of gcc, the related around 'pep_enable_stdcall_fixup' 
can be removed completly for this target (There are no '@xx' for this 
target at all). I updated for this target the autofilter_symbollist_i386 
list, too.
 
Further I detected that the test-case of ld-pe : direct fails, because the 
shared object detection wasn't merged from pe to pep.

ChangeLog for ld

2007-07-24  Kai Tietz  <kai.tietz@onevision.com>

        * emultempl/pep.em: (pep_enable_stdcall_fixup): Set to value 1.
        gld_xxx_recognized_file: Use pep_bfd_is_dll for detection of 
shared
        objects.
        * pe-dll.c: (autofilter_symbollist_i386): Define set
        for amd64 mingw target.

Cheers,
 i.A. Kai Tietz
