I'm trying to build a Win32 DLL with separate debug symbols, but I can't
seem to get GDB to automatically load a symbol file using the PE build-id
support added in ld 2.25.  I'm running on Fedora 21 x86_64, with a gdb
built from binutils-gdb HEAD (3e95021) and configured with
"--target=i686-w64-mingw32".

Sorry, this was not something that I needed, so I never got around tolooking at what was needed to hook this up in gdb.

At the moment, fetching the build-id for gdb is only implemented for ELFfiles (See gdb/build-ic.c:build_id_bfd_get())

It should be pretty straightforward to extend that to handle PE files aswell, and add an interface to get the PE build-id out of BFD...
