Lua on ARM baremetal

[Andre Leiradella <andre@...>]

Hi All,

This is almost one year old now but I think it's interesting enough to 
share: stock Lua running on a Raspberry Pi without an OS [1,2].

No changes were made to Lua's source code. There was an issue with 
printing 64-bit integers but it was solved by correctly configuring 
Newlib [3].

Cheers,

Andre
