* add separate variable for configuration options generated from
PACKAGECONFIG setting, this helps other bbclasses and recipes
to take advantage of PACKAGECONFIG mechanism, without including
other options from EXTRA_OECONF
* e.g. meta-qt5 recipes are abusing EXTRA_OECONF to get options
from PACKAGECONFIG:
EXTRA_QMAKEVARS_PRE +=
but with
conf/distro/include/no-static-libs.inc
it means getting --disable-static as invalid option inside
EXTRA_QMAKEVARS_PRE as reported by Alexandre Belloni who tried
to use poky with meta-qt5.
* once we migrate all bbclasses and recipes to PACKAGECONFIG_CONFARGS
we should also restrict EXTRA_OECONF append only to autotools.bbclass
like I did for cmake.bbclass
