On Solaris 7, I'm getting a link error
cc -O -g -o test-connect test-connect.o libtests.a ../gllib/libgnu.a
libtests.a -lsocket
ild: (undefined symbol) inet_pton -- referenced in the text segment of
test-connect.o
*** Error code 5
because inet_pton is declared in the system's <arpa/inet.h> but gnulib has not
found the function in any library. The reason is that on that version of
Solaris, it's found in libresolv, not in libnsl. Likewise for inet_ntop.
This patch fixes it.

inet_ntop, inet_pton: Look for it also in libresolv.
* m4/inet_ntop.m4 (gl_FUNC_INET_NTOP): If the function was not found in
libnsl, search for it in libresolv.
* m4/inet_pton.m4 (gl_FUNC_INET_PTON): Likewise.
Needed on Solaris 7.
