Subject: ["@", "ssl", "", "crypto"] default TARGET_ARCH to ARCH

In this way, we achieve that the target to be used by targets outside
this repository is the same, regardless if an unset TARGET_ARCH
is replaced by the value of ARCH. This is an assumption consuming
targets (legitimately) make and that was violated if one of those
configs is in target-level cache, but not the other.
