Great.

The goal is to be able to *create* complete and useful .pc files. I am not sure
if the RTEMS build system could be turned around to use .pc, it may, but until
then I suggest we convert the .cfg files in the BSPS to .pc files.

This seems like a sensible approach.

I think the first step is to look at the existing .cfg files and to see what is
happening. It will take time and is a bit boring but I feel you will quickly see
which ones have major differences. I lot of files are copies so I suspect they
will fall into patterns or groups.
