[OE-core] [PATCH 43/45] default-versions.inc: Make PREFERRED_VERSION_openssl* overwritable

[Armin Kuster]

From: Stefan Lendl <ste.lendl at gmail.com>

defaultsetup.conf and therefore default-versions.inc is sourced pretty late in bitbake.conf.
default-versions.inc overwrites previous assignments of PREFERRED_VERSION_openssl.
Assigning it with ?= allows other .conf files to assign correctly.
in particular assignment in conf/local.conf and machine config is used instead of default.

(From OE-Core rev: c9786adf81434e2d58247f55cf80fdd3131121e7)
