[Minios-devel] [UNIKRAFT/LIBPSIMD PATCH 3/3] Initial port of psimd on Unikraft

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

This is our initial port of psimd to Unikraft as an external library.
The intel-intrinsics library is required. When adding the library to
the dependency list, psimd should stay after intel-intrinsics.
(e.g. ...:$(UK_LIBS)/intel-intrinsics:$(UK_LIBS)/psimd...).
