We had added the --disable-curl to EXTRA_OECONF, but there is an
EXTRA_OECONF_virtclass-nativesdk += "foo", the
"EXTRA_OECONF_virtclass-nativesdk +=" equals to
"EXTRA_OECONF_virtclass-nativesdk =" (the "+" has no effect here), so we
should add the "--disable-curl" to EXTRA_OECONF_virtclass-nativesdk.
And change the "+=" to "=" to not confuse people.
