Use strerror_r in safe_strerror if available
Also stores the result in a thread-local static variable and changes the return value to a const char*. This is already important because Guile creates threads and Python can create threads, but with the patch series here: https://gnutoolchain-gerrit.osci.io/r/c/binutils-gdb/+/176 GDB itself will create threads, too. gdb/ChangeLog: 2019-10-31 Christian Biesinger <cbiesinger@google.com> * configure: Regenerate. * configure.ac: Check for strerror_r. * gdbsupport/common-utils.h (safe_strerror): Change return value to const char * and document that this function is now threadsafe. * gdbsupport/posix-strerror.c (safe_strerror): Make buf thread_local and call strerror_r, if available. * utils.c (perror_string): Update. (print_sys_errmsg): Update. Change-Id: I81048fbaf148035c221c528727f7efe58ba528eb
