[5.9] Compile error on x86 32bit linux machine

[TuITeraz]

I'm trying to compile net-snmp 5.9 from sources on x86 32bit linux machne:

Configure parameters:
./configure --without-perl-modules --disable-embedded-perl --enable-ipv6 --prefix=/usr/ --with-defaults --enable-new-features --with-default-snmp-version=2 --with-systemd --with-security-modules="usm tsm" --enable-blumenthal-aes --with-transports="DTLSUDP" --with-install-prefix="/home/user/net-snmp-5.9/package"

make ends with an error:

mibgroup/ip-mib/data_access/.libs/ipaddress_ioctl.o: In function `_netsnmp_ioctl_ipaddress_container_load_v4':
/home/user/net-snmp-5.9/agent/mibgroup/ip-mib/data_access/ipaddress_ioctl.c:248: undefined reference to `netsnmp_access_other_info_get'

I've encountered the same problem:

I could get it compiled using this patch:

    agent/mibgroup/ip-mib/data_access/ipaddress_ioctl.c: fix unavailable netsnmp_access_other_info_get function
    
    netsnmp_access_other_info_get is not compiled if HAVE_LINUX_RTNETLINK_H is not defined

Problem is that <linux/rtnetlink.h> is not available on older kernels, netsnmp_access_other_info_get was therefore not compiled.
