Steps to reproduce:

1. I configured with by pointing to additional lib-dirs:

LDFLAGS="-L/opt/csw/lib/sparcv9 -L/.SUNWnative/lib/sparcv9" ./configure --enable-agent

1. run make

Result:

Linking zabbix_agentd fails:

I would transform this into a one liner:

Undefined symbol round first referenced }}{{in file }}{{zabbix_agentd-procstat.o

Expected:
Compilation should succeed.
