Hello Jini,

In general this looks pretty good, but it's also breaking some new 
ground as it's adding generation of native source in the java gensrc 
step. Mixing native code with the java code that the genrcs targets and 
gensrc output directories are meant for seems ok for now, but may cause 
trouble in the future. I'm going to accept it for now though.

In Gensrc-jdk.hotspot.agent.gmk: Please put the new macosx stuff in its 
own section (as delimited by the 80x # lines) and put that whole thing 
inside a conditional for macosx. Also please break line 47 (for recipe 
lines, indent with tab and 4 additional spaces for continuation [1]).

In Lib-jdk.hotspot.agent.gmk: I believe adding extra src should be 
enough as that will implicitly add the same directories as header dirs 
by default. At least that's the intention.
