[PATCH 1/2] openssl_1.1: avoid using += with an over-ride

[Andre McCurdy <armccurdy@gmail.com>]

Using += with an over-ride can be a source of confusion so try to
avoid the construct in core recipes.

The current usage is incorrect and prevents the aarch64 and musl
specific config options from being active together.
