[PATCH 3/3] build: Disable some optimizations if TRACE_BFD is enabled

[Andrei Otcheretianski]

From: Benjamin Berg <benjamin.berg at intel.com>

When TRACE_BFD is enabled we need to be able to fetch stack traces.
However, some required functions might be inlined by the compiler or
hidden due to tail call optimizatons. Add -fno-inline and
-fno-optimize-sibling-calls to avoid these optimizations.
