[PATCH] Use dwarf-2 by default on OpenBSD and FreeBSD

[Dimitry Andric]

For FreeBSD, I was practically forced to revert the default to DWARF2, after many complaints from our users and developers.  The main reason is that our version of gdb is still stuck in the stone (GPLv2) age, just like our version of GNU ld (and other binutils, inasmuch we use them).  We do have lldb in the tree, but it isn't built by default, and it isn't yet feasible to use for all our architectures.

That said, I would personally have preferred dumping our old gdb, and forcing users to install the much newer gdb (7.x) port, but that wasn't acceptable, unfortunately.  There is quite a large amount of inertia, and I fear DWARF2 will still be the default for many years (basically, for the entire lifetime of FreeBSD 11.x).
