libgccjit 5.2 on Mac OSX Yosemite

[Dibyendu Majumdar <mobile@majumdar.org.uk>]

Hi

I tried building gcc 5.2 on Mac OSX but could not get the linking to
work. Then fortunately found that homebrew has a formula for deploy
gcc 5.2 with jit enabled.

All installed and then built Ravi successfully. But when I try to run
Ravi any attempt to invoke the JIT fails with:

Lua 5.3.1  Copyright (C) 1994-2015 Lua.org, PUC-Rio

Any clues?

I had set PATH and LD_LIBRARY_PATH.
