FR-V PLT audit

[Alexandre Oliva <aoliva at redhat dot com>]

The FR-V port doesn't support profiling (yet?), and so we never
actually lay out the structure that pltenter/exit functions rely on,
but it looks like we must define them anyway.  Here are the
definitions.

	* sysdeps/generic/ldsodefs.h (struct audit_ifaces): Add frv
	members.
