You have something similar to this

LDFLAGS=	-L/usr/pkg/lib

in /etc/make.conf?  Try commenting out, or use a custom make.conf
only for {build,install}{kernel,world} to avoid this.  You can use
$__MAKE_CONF to switch make.conf files:

cd /usr/src
env __MAKE_CONF=/etc/src.conf make buildworld

Cheers.
