Adding a new library is not necessarily as trivially as just adding 
flags to the command line.

I suggest you take a look at how the libffi library is added to Hotspot 
when building Zero. Search for LIBFFI_LIBS in the make directory to see 
how it is setup and used. Use this as inspiration for your own library.
