It's not needed. Meson build does not allow you to go arbitrarily disabling
libraries - exactly for this reason, to save us littering other build files
with all sorts of checks for various libraries. Only those libraries which
are unsupported on a particular platform need to be checked for - all core
libraries are always available. I'm sure if you looked at it, we should
have an awful lot more checks in our Makefiles for library disabling, not
to mention the fact that EAL, mbuf, mempool libraries are possible to
disable, even though doing so will result in an unbuildable mess.
