When dtrace starts, it tries to detect if the dtrace klds are loaded, and if not, it loads them by loading the dtraceall kld. This module depends on most dtrace modules, including systrace for the native freebsd and freebsd32 ABIs. However, it does not depend on the systrace_linux klds, as they in turn depend on the linux ABI klds, and we don't want to load an ABI module that the user has not explicitly requested. This can leave a naive user in a state where they think all syscall providers have been loaded, yet linux ABI syscalls are "invisible" to dtrace. To fix this, check to see if the linux ABI modules are loaded. If they are, then load their systrace klds.
