Turn off lldb debug tuning by default for FreeBSD

Authored by dim on Jan 7 2016, 1:42 PM.



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.

I advocated for the lldb tuning by default on FreeBSD originally, but I didn't fully understand the implications. It turns out we're just not ready yet. So, LGTM.

LGTM. Somebody had actually asked for the default to be LLDB, originally, but I'm not invested which way the default goes.

That was me. I didn't quite understand what was going to change though and subsequently realized there's more work we'll need to do in gdb, and other build tools before we can set this default on FreeBSD.
