PATCH 1/1 wireshark: fix inet_pton detection

Patch configure.ac to not assume broken inet_pton in case of cross compiling (avoids double definition), similare patch is used for OpenEmbedded (see [1]).

Fixes [2]:

host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libc.a(ntop.os): In function `inet_pton':
ntop.c:(.text+0x4b4): multiple definition of `inet_pton' wsutil/.libs/libwsutil.a(inet_pton.o):inet_pton.c:(.text+0xe0): first defined here
collect2: error: ld returned 1 exit status

PATCH 1/1 wireshark: fix inet_pton detection

Dear Peter Seiderer,

Quoted 14 lines · Peter Seiderer

Patch configure.ac to not assume broken inet_pton in case of cross compiling (avoids double definition), similare patch is used for OpenEmbedded (see [1]).

Fixes [2]:

host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libc.a(ntop.os): In function `inet_pton':
ntop.c:(.text+0x4b4): multiple definition of `inet_pton' wsutil/.libs/libwsutil.a(inet_pton.o):inet_pton.c:(.text+0xe0): first defined here

I've applied, but I'm not super happy with the proposed solution because it's not upstreamable. Can you instead work on a different patch that adds a autoconf cache variable that allows to override the result of the "inet_pton is broken" test without patching the configure.ac ?

See
http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Caching-Results.html
for more details.

Thanks!

Thomas
