Subject: Don't copy from %target to %config so much, see %config as a complement
X-Git-Tag: OpenSSL_1_1_0-pre4~399
X-Git-Url: https://git.openssl.org/?a=commitdiff_plain;h=2952b9b8115bdd852fb226e918f8b6d6a4a0bea2;hp=9c62a279fecc4ccb95ea55e1ba36470f3eab8775;p=openssl.git

Don't copy from %target to %config so much, see %config as a complement

We copied $target{cflags}, $target{defines} and a few more to %config,
just to add to the entries.  Avoid doing so, and let the build templates
deal with combining the two.

There are a few cases where we still fiddle with %target, but that's
acceptable.
