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. gdb/ChangeLog: 2019-11-15 Christian Biesinger <cbiesinger@google.com> * gdbsupport/common-defs.h: Include time.h before pathmax.h to avoid compile errors. gnulib/ChangeLog: 2019-11-15 Christian Biesinger <cbiesinger@google.com> * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * config.in: Regenerate. * configure: Regenerate. * import/Makefile.am: Update. * import/Makefile.in: Regenerate. * import/m4/gnulib-cache.m4: Update. * import/m4/gnulib-comp.m4: Update. * import/m4/time_r.m4: New file. * import/time_r.c: New file. * update-gnulib.sh: Import time_r.
