# The call to backtrace() function fails for ARC, because for some
# reason the unwinder from libgcc returns early. Thus the usage of
# backtrace() should be disabled in perf explicitly: at build time
# backtrace() appears to be available, but it fails at runtime: the
# backtrace will contain only several functions from the top of stack,
# instead of the complete backtrace.
