imported Iakin's public domain jcpuid library allowing the detection of CPU types from java

imported Iakin's modifications to jbigi to use the jcpuid library in detecting what jbigi implementation to load
imported and slightly updated Iakin's scripts to build jbigi for lots of architectures
(yay iakin!)
