According to the lastest glibc, bsd_signal function is just declared
when POSIX.1-2008(or newer) instead of POSIX.1-2001 is not set since
glibc v2.26.
Please see the following code from signal/signal.h:
-----------------------------------------------------------------
#if defined __USE_XOPEN_EXTENDED && !defined __USE_XOPEN2K8
/* The X/Open definition of `signal' conflicts with the BSD version.
So they defined another function `bsd_signal'. */
extern __sighandler_t bsd_signal (int __sig, __sighandler_t __handler)
__THROW;
#endif
