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

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

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