C+1: fix mac build error by merging r7966: scons: Pass -Wl linker flags to fbc correctly when using linkgcc=0 (added FBLINKERFLAGS)
    
    linkgcc=0 now works to link Game and Custom again!
    Works on Mac 32/64bit FB 1.06, Linux 32/64bit FB 0.23/1.06. Didn't test on
    Windows.
    
    Only the last -Wl arg to fbc takes effect, so Framework args weren't getting
    passed to the linker.
    
    Also, don't pass the optional FRAMEWORKS_PATH if it doesn't exist (avoid an error)
