When building a cross-kgdb, suppress the registration of the

standard core target by declaring coreops_suppress_target with
initializer. This is also happening for non-cross kgdb, by
virtue of having fbsd-threads.c in libgdb and having it do the
exact same thing. Since fbsd-threads.c is not included in in
libgdb when building a cross debugger, we ended up with more
than 1 core file targets (the standard gdb core file target and
kgdb's libkvm based core file target) and this behaves the same
as not having a core target at all.

* there are multiple core_stratum targets, the find_core_target() function
* won't know which one to return and returns none. We need it to return
* our target. We only have to do that when we're building a cross-debugger
* because fbsd-threads.c is part of a native debugger and it too defines
* coreops_suppress_target with 1 as the initializer.
