Fixed the below bugs: 1) Bug related to build flag V=1: if the flag was V=0, building with ROMLIB would fail. 2) Due to a syntax bug in genwrappers.sh, index file entries marked as "patch" or "reserved" were ignored. 3) Added a prepending hash to constants that genwrappers is generating. 4) Due to broken dependencies, currently the inclusion functionality is intentionally not utilised. This is why the contents of romlib/jmptbl.i have been copied to platform specific jmptbl.i files. As a result of the broken dependencies, when changing the index files, e.g. patching functions, a clean build is always required. This is a known issue that will be fixed in the future.
