- Optimise ROTable accesses and interface
This includes some refinements to the ROTable cache which remove the linker cludges on the CROSS_COMPILE builds. Also keyhole tweaks to some of the Lua VM code to implrove runtimes.
I also noticed some compile time warnings during the build; the change to uz_unzip.c doesn't impact the compiled code, but does remove the compiler warnings.
Use separate names for the integer and float `luac.cross` binaries. Also adds local/lua directory which is already supported by tools makefile to build LFS image.
