There are '&& exists(/usr/local/lib/${EOPENSSL}/libtls.a)' where EOPENSSL
expands to eopenssl40, and without libretls4, this check will be false.

Without libretls4 it will still compile and run the basic regress tests
like test-roa.c, etc. But it won't compile rpki-client against libretls4
and build/obj/rpki-client won't exist (or be old).
