Log Message:
syslog-ng overloads sigaction() with its own version, and calls the libc
sigaction() with a dlsym call. On NetBSD this ends up calling the compatibility
sigaction() which fails with ENOSYS if COMPAT_13 is not in the kernel.
Even with COMPAT_13 it would be incorrect because we call the compat
sigaction() with the non-compat arguments.

On NetBSD, fix this by calling explicitely __libc_sigaction14().
