[bugfix]configure: fix error when cross-compile
While cross-compile, ./configure --host=xxx will output:
"checking whether printf(3) supports the z length modifier...
configure: error: in `/${path_to_tcpdump}/tcpdump':"
That is casued by AC_RUN_IFELSE, as describe in
"https://www.gnu.org/software/autoconf/manual/autoconf-2.63/html_node/Runtime.html"
, if AC_RUN_IFELSE do not have cross-compile option, configure prints an error message and exits.
