Fix clang compiler warnings on FreeBSD in erts
The following are deliberately left, as I have only a list of compiler warnings and no system to test on: hipe/hipe_x86_signal.c:264:5: warning: no previous prototype for function '_sigaction' [-Wmissing-prototypes] int __SIGACTION(int signum, const struct sigaction *act, struct sigaction *oldact) ^ hipe/hipe_x86_signal.c:222:21: note: expanded from macro '__SIGACTION' ^ 1 warning generated. sys/unix/sys_float.c:835:16: warning: declaration of 'struct exception' will not be visible outside of this function [-Wvisibility] matherr(struct exception *exc) ^ sys/unix/sys_float.c:835:1: warning: no previous prototype for function 'matherr' [-Wmissing-prototypes] matherr(struct exception *exc) ^ 2 warnings generated. drivers/unix/unix_efile.c:1504:11: warning: implicit declaration of function 'sendfile' [-Wimplicit-function-declaration] retval = sendfile(in_fd, out_fd, *offset, SENDFILE_CHUNK_SIZE, ^ 1 warning generated.
