X-Bullshit: encrypted deep-learning information-scale API 

I am building under Virtual box with u9fs fs served from linux.
I have encountered many small issues in getting everything setup and so 
I have had to restart the build
process frequently.
The build process always rebuilds the libraries even though they have 
not changed and do not require rebuilding. This make the whole build 
process unduly painful.

I have tried binding /sys/sys/cmd/mklib over mksyslib but the mklib does 
not handle a dependency where no targets needing rebuilding. Ie 
libname(): don't know how to build.

Anyone got any advice on how I can restart the build without having to 
spend 30minutes churning over all the libraries or how to change the 
makefile to skip them if they are built?

cheers.
