[yocto] Does PACKAGECONFIG only apply to autotools recipes

[Martin Jansa]

It's applied in PACKAGECONFIG_CONFARGS variable and various bbclasses (and
also various recipes) use this variable where needed, see git grep:

meta/classes/base.bbclass:        appendVar('PACKAGECONFIG_CONFARGS',
extraconf)

meta/classes/autotools.bbclass:EXTRA_OECONF_append = "
${PACKAGECONFIG_CONFARGS}"
meta/classes/cmake.bbclass:EXTRA_OECMAKE_append = "
${PACKAGECONFIG_CONFARGS}"
meta/classes/meson.bbclass:EXTRA_OEMESON += "${PACKAGECONFIG_CONFARGS}"
meta/classes/waf.bbclass:EXTRA_OECONF_append = " ${PACKAGECONFIG_CONFARGS}"

meta/recipes-graphics/glew/glew_2.1.0.bb:EXTRA_OEMAKE =
"${PACKAGECONFIG_CONFARGS} \

It used to be included in EXTRA_OECONF by default, before:
