[rrd-users] Missing lib options in Makefile.PL for interix

[Steven Hartland]

When compiling under interix I needed to edit Makefile.PL from:
'dynamic_lib'  => {'OTHERLDFLAGS' => "$librrd -lm"},
to:
'dynamic_lib'  => {'OTHERLDFLAGS' => "$librrd -lm -lpng12 -lart_lgpl_2 -lfreetype"},

Without doing so make test failed:
perl-shared> make test
PERL_DL_NONLAZY=1 /bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t

Stop.

Pretty sure this change will also be safe under other OS's but will need testing.
