This is a modified version of this patch:

[#7660] Solaris 10 x86 support (Makefiles)

Hopefully it will not mess up anything for anyone else.  I removed
some hardcoded static libs and made NAN_*_LIB definitions so they could be 
overridden, to allow greater flexability.

Let me know if there are any problems/questions.
