RFR: 2228582: Licensee source bundle tries to compile JFR

[Erik Gahlin]

Hi,

Could you please review this fix for licensee source bundle. This is a 
forward port of:

https://bugs.openjdk.java.net/browse/JDK-8001697

I removed:

ifndef OPENJDK
ifndef JAVASE_EMBEDDED

and only check for BUILD_JFR. Not sure if it is correct? I tried to 
build with:

make newbuild=true source

and I didn't get any errors on standard out, but I'm not sure how 
interpret the result. It would be good if someone more experienced with 
licensee builds could verify the results before checking in.

Thanks
Erik
