* copyright.py (EXCLUDE_LIST): Add gdb/common/glibc_thread_db.h.
Attempting to build gdbserver with our copy of thread_db.h yields:
In file included from ../../../src/gdb/gdbserver/../common/gdb_thread_db.h:4:0,
from ../../../src/gdb/gdbserver/thread-db.c:30:
../../../src/gdb/gdbserver/../common/glibc_thread_db.h:108:3: error: unknown type name ‘uint32_t’

../../../src/gdb/gdbserver/../common/glibc_thread_db.h:270:3: error: unknown type name ‘intptr_t’
We used to have a workaround for this, but the patch to import
gnulib's stdint.h removed it:
http://www.sourceware.org/ml/gdb-patches/2008-06/msg00050.html
and defs.h made to always include stdint.h. However, gdbserver
doesn't include stdint.h in its equivalent server.h.
Rather than working around the issue, I've imported a more recent
version from glibc, which itself includes <stdint.h>. Other than
copyright years and FSF snail mail address, the file hasn't been
touched since 2003 in glibc. AFAICS, our version was updated last in
2000-09-03.
A note on the apparent license change: before the previous patch, this
file's contents were part of gdb_thread_db.h, and we can see that its
license's text was changed in this patch
<http://sourceware.org/ml/gdb-patches/2009-03/msg00251.html>. That
was certainly just an easy to overlook grep/sed mistake that fell
through the cracks.

* glibc_thread_db.h: Update from upstream glibc
(git 568035b7874a099087b77f7bba3e36a1173787b0).
Having this on a separate file makes it easier to import a new version
-- one can just copy over instead of having to care about preserving
the GDB-specific bits.

* common/gdb_thread_db.h [!HAVE_THREAD_DB_H]: Factor out to ...
* common/glibc_thread_db.h: ... this new file ...
* common/gdb_thread_db.h [!HAVE_THREAD_DB_H]: ... and include it.
This patch:
http://sourceware.org/ml/gdb-patches/2009-04/msg00115.html
Changed behaviour by only defining LIBTHREAD_DB_SO if thread_db.h exists. The
definition of LIBTHREAD_DB_SO and LIBTHREAD_DB_SEARCH_PATH should be moved
outside of #ifdef HAVE_THREAD_DB_H.
This is based on a patch attached to the PR, however, it needed a
tweak, as it was it broke the HAVE_THREAD_DB_H path.

non_got_ref may not be set when building shared library. We need to set
non_got_ref if there are any non-PIC relocations. But we only did this
when there were no PLT/GOT relocations. It failed when there is a PLT
relocation. This checkin moves the non_got_ref check out.
