sandbox: Allow "clock_gettime64" syscall where defined
On 32-bit architectures where Linux provides the "clock_gettime64" system call, including i386, glibc uses it in place of "clock_gettime". Modify the sandbox implementation to match, to prevent Tor's monotonic-time functions (in src/lib/time/compat_time.c) failing when the sandbox is active. --- src/lib/sandbox/sandbox.c | 4 ++++ 1 file changed, 4 insertions(+)
