gdbstub: Only build libgdb_user.fa / libgdb_softmmu.fa if necessary
It is pointless to build libgdb_user.fa in a system-only build
(or libgdb_softmmu.fa in a user-only build). Besides, in some
restricted build configurations, some APIs might be restricted /
not available. Example in a KVM-only builds where TCG is disabled:
$ ninja qemu-system-x86_64

ninja: build stopped: subcommand failed.
