[Minios-devel] [UNIKRAFT PATCH] build: Make a platform configurable

[Sharan Santhanam <sharan.santhanam@xxxxxxxxx>]

In our build system, default platform libraries are included even while
the platform is disabled. This patch ensures that the platforms are built
only when the corresponding CONFIG is enabled.
