find: compiler: No such file or directory

Since compiler directory move to https://github.com/grumpyhome/grumpy/tree/master/grumpy-tools-src/grumpy_tools/compiler

We have to update the Makefile of https://github.com/grumpyhome/grumpy/blob/master/grumpy-runtime-src/Makefile
Also, it should make to enable to run unit tests also.

I think that @alanjds is a proper person to do it. I don't know the history which is related with why the compiler directory is moved.

Lots of the Makefile stuff got unnecessary after grumpy-tools became a separate package.

This compiler folder is no longer used, nor most of the bin folder.

My Makefile wisdom is not par for this one, but I will chop the compiler part and let's see if it still works 😉
