Subject: Turn off lldb debug tuning by default for FreeBSD
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=b60a342483e1ec9f1da9419f252f23aae8571843;hp=8bc44fb2b48ea8c031963707488050131be8b9f0

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.
