RFR: [9] 8043340: [macosx] Fix hard-wired paths to JavaVM.framework

[David DeHaven]

> Tested on 10.8 with Xcode 5.1 and Xcode 4.6.3 and on a clean 10.9 system with Xcode 5.1 against jdk9/hs. I will submit a JPRT sanity run shortly.

I just ran into an issue in hotspot with Xcode 5.1 on 10.8 with older command line tools (from Xcode 4) installed. We'll need to use -isysroot in conjunction with -iframeworks

I'll update the patches with this and the recommendations I've gotten so far tonight.
