[Coco] Announcement : Nitros-9 C compiler tool cross chain for Linux

[Bill Pierce]

Walter, thanks for the info. I may try creating makefiles for everything like the NitrOS9 repo. This could simplify the process.

Tip:

There is no overall make file.  You'll have to go into the build
directory for each component and type make.

Make sure you are using a 32 bit build environment. It simply won't work
in 64 bit!
