Allow gdb to find debug symbols file by build-id for PE file format also
This promotes BFD's struct elf_build_id to the generic struct bfd_build_id,
populated when an ELF or PE BFD is read.
gdb is updated to use that, and to use the build-id to find symbols for PE files
also.
There is currently no generic way to extract the build-id from an object file,
perhaps an option to objdump to do this might make sense?
On x86_64-pc-cygwin, gdb's sepdebug.exp changes:
-# of unsupported tests 1
+# of expected passes 90
I don't seem to get consistent testsuite runs on i686-linux-gnu, but there
don't appear to be any regressions.
