net/net-snmp configure failure under -current

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

Hi,

This package fails configure as recent libwrap.so refers to libblocklist:
...
configure:25104: result: no
configure:25117: checking for TCP wrappers library -lwrap linked with -lnsl
configure:25133: gcc -o conftest -DNETSNMP_ENABLE_IPV6

configure:25133: $? = 1
configure: failed program was/

...

Adding

LDFLAGS+=         -lblocklist

to the Makefile allows the build to complete, but surely this is not
the right and proper thing to do, as it should be conditional to the
OS version I guess.
