3f0ead9d4e yay buildroot passes a decent amount of tests now 
gets through the first 15k instructions, that's good enough for now
also slight change to string parsing in busybear testbench

6954e6df4c buildroot: sim is now running!

4f97e9e761 start to add buildroot testbench

I think it might be time to finally rename nearly 'busybear' thing to 'linux'
