pcap link patch

[David Scott Page]

Hi,

On Solaris, a dll (.so) not in the default (system) library search
path needs a search path explicity specified during the link. For
libpcap.so, I need to define PCAP_LIBS='-L/opt/sfw/lib -R/opt/sfw/lib'
in order to link and subsequently load the program without using
LD_LIBRARY_PATH (which should be relegated to debugging activities).
I don't want to define LDFLAGS, since this applies to linking in
general. The enclosed patch accomodates this.
