I am not seeing an immediate way to fix this optimally. The go-to 
solution to this class of issues is to just make
the #!/usr/bin/env <interpreter>. The issue is that there is an extra 
-f, which with /usr/bin/env, will not work. The awk manual also implies 
this is not optional for standalone scripts. I think we can create a 
wrapper, or maybe we already have such a wrapper?

It takes quite a while on my computer and often i get out of disk space. 
I tried asking the linaro guys for a tuxsuite token but no answer yet. 
If you have some way of getting resources to make builds let me know.
