base.bbclass: define PACKAGECONFIG_CONFARGS before only sometimes appending to it
* just to make sure it's expaned by bitbake before it gets
executed in shell
* e.g. with cmake.bbclass and cmake recipe (any recipe without
PACKAGECONFIG options have this issue) it looks like this:
bitbake -e cmake | grep EXTRA_OECMAKE=
EXTRA_OECMAKE=" -DCMAKE_DOC_DIR=share/doc/cmake-3.14
-DCMAKE_USE_SYSTEM_LIBRARIES=1 -DCMAKE_USE_SYSTEM_LIBRARY_JSONCPP=0
-DCMAKE_USE_SYSTEM_LIBRARY_LIBUV=0
-DCMAKE_USE_SYSTEM_LIBRARY_LIBRHASH=0 -DKWSYS_CHAR_IS_SIGNED=1
-DBUILD_CursesDialog=0 -DKWSYS_LFS_WORKS=1
\${PACKAGECONFIG_CONFARGS}"
