Compile for 8051 using sdcc

A host for development is Linux PC.

The compiler used is sdcc.

The build scripts used for compiling for 8051 are similar to the Linux build scripts. The main difference is that the names of intermediate files: sdcc create a number of files. One of the problem that is not yet resolved, is that sdcc debugger does not work if the binary is linked from libraries.

Instructions:

ln -s build-configurations/Platform-8051 Platform
ln -s build-configurations/Options-8051-sim-debug Options
make rebuild
