Fixes [YOCTO #10183]
Added a new variable entry for the PACKAGECONFIG_CONFARGS variable.
With the introduction of the new PACKAGECONFIG_CONFARGS variable,
many places in the mainstream YP documentation that referenced
how to pass configure arguments using EXTRA_OECONF needed to also
make mention of this new variable. I added many cross-references
to the new variable.
