Dimitry Andric b60a342483 Turn off lldb debug tuning by default for FreeBSD
Summary:
In rL242338, debugger tuning was introduced, and the tuning for FreeBSD
was set to lldb by default.  However, for the foreseeable future we
still need to default to gdb tuning, since lldb is not ready for all of
FreeBSD's architectures, and some system tools (like objcopy, etc) have
not yet been adapted to cope with the lldb tuned format, which has
.apple sections.

Therefore, let FreeBSD use gdb by default for now.
