Import the time_r gnulib module
This allows GDB to use localtime_r unconditionally.
See https://lists.gnu.org/archive/html/bug-gnulib/2019-11/msg00022.html
for details on the compile error mentioned below.

2019-11-15 Christian Biesinger <cbiesinger@google.com>
* gdbsupport/common-defs.h: Include time.h before pathmax.h to
avoid compile errors.
