Subject: [PATCH 5/6] perf tools: disable JVMTI if no ELF support available
Date: Wed, 12 Apr 2017 10:07:45 -0700	[thread overview]
Message-ID: <20170412170745.26620-1-davidcc@google.com> (raw)
In-Reply-To: <20170412081921.GD17517@krava>

The build of JVMTI depends on LIBELF (-lelf). Make Makefile.conf
check this dependendancy and notify user when not present.

v2: Comma nitpicking.
