[Minios-devel] [UNIKRAFT/LIBZLIB PATCH v4 2/3] Add Makefile.uk

[Felipe Huici <felipe.huici@xxxxxxxxx>]

This is a port of zlib to Unikraft as an external library. It requires
libc, so in your application Makefile the library dependency list
should read:

           LIBS := ...:$(UK_LIBS)/newlib:$(UK_LIBS)/zlib:...
