[Minios-devel] [UNIKRAFT/LIBCXXABI PATCH v3 2/3] Initial public release: configuration and build files

[Vlad-Andrei BĂDOIU (78692) <vlad_andrei.badoiu@xxxxxxxxxxxxxxx>]

This is our initial port of libcxxabi to Unikraft as external
library. Libc is required.

In the dependency list it should stay as follows:
...:$(UK_LIBS)/libunwind:$(UK_LIBS)/compiler-rt:
$(UK_LIBS)/libcxxabi:$(UK_LIBS)/libcxx:$(UK_LIBS)/newlib:...

Signed-off-by: Vlad-Andrei Badoiu <vlad_andrei.badoiu@xxxxxxxxxxxxxxx>
