[Minios-devel] [UNIKRAFT/PTHREADPOOL PATCH 3/3] Initial port of pthreadpool to Unikraft

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

This is our initial port of fp16 to Unikraft as an external library. Libfxdiv
and pthreads is required. When adding the library to the dependency list it
should stay after libfxdiv
(e.g. ...:$(UK_LIBS)/libfxdiv:$(UK_LIBS)/libpthreadpool:...).
