Can't build jdk9-dev due to conflicting includes

[Daniel D. Daugherty]

Adding the Serviceability group since SA belongs to them...

I believe that this issue is solved by this changeset:

Changeset: 64e35dfa4ff5
Author:    jwilhelm
Date:      2014-06-13 17:07 -0400
URL: http://hg.openjdk.java.net/jdk9/hs/hotspot/rev/64e35dfa4ff5

8046408: Build failure from multiple ptrace.h
Summary: prefer <sys/ptrace.h> over <linux/ptrace.h>
Reviewed-by: sla, mikael

That changeset was pushed to JDK9-hs yesterday which means it
should be in JDK9-dev next week (presuming all goes well with
the weekend PIT of today's snapshot).
