Resetting Eclipse C compiler choice

HAH, got it.

Apparently if you update the tools it can break the BSPs. Then Eclipse will look for gcc instead of, say, arm-rtems4.11-gcc.

So, the easiest thing is to expunge everything, source-builder the tools, git the source, and build the source and Eclipse will pick up the proper tools.

Now, wouldn’t it be cool if source-builder could also download and build the RTEMS source? Or change the name to tool-builder?
