Subject: [PATCH] configure.ac: fix --without-libdnet
|
|
Allow the user to disable libdnet check through --without-libdnet.
|
This option is useful to cross-compile tcpreplay to avoid build failures
|
if libdnet is installed on host but not on target, see
|
https://bugs.buildroot.org/show_bug.cgi?id=12096
