[yocto] net-snmp_5.8.bb failed to compile

[Simon Chamlian]

Replacing 'filter'  by 'contains' will do the trick (will compile)

- PACKAGECONFIG ??= "${@bb.utils.filter('DISTRO_FEATURES', 'ipv6', d)}"
+PACKAGECONFIG ??= "${@bb.utils.contains('DISTRO_FEATURES', 'ipv6', 'ipv6',
'', d)}"


Note that I get the following warning:

WARNING: net-snmp-5.8-r0 do_package_qa: QA Issue: net-snmp-client rdepends
on libpcap, but it isn't a build dependency, missing libpcap in DEPENDS or
PACKAGECONFIG? [build-deps]
