[Minios-devel] [UNIKRAFT/RUBY PATCH 05/16] core: Build core functionality

[Costin Lupu <costin.lupu@xxxxxxxxx>]

From: Andrei Gogonea <andrei.gogonea09@xxxxxxxxx>

With these changes we only build the Ruby interpreter. In the following patches
we will add Ruby extensions and encodings as well. The original Ruby build
provides what is called 'miniruby' - the minimalistic variant of the Ruby
intepretor and which doesn't have any extensions. We used the same idea to
provide a minimalistic version for Unikraft when the mini configuration is
checked via menuconfig.
