Subject: Respect --without-chroot correctly
X-Git-Tag: tcpdump-4.1.1~4
X-Git-Url: https://git.tcpdump.org/tcpdump/commitdiff_plain/a6e6091ef16cd3038d2364d4ada82ab51cbd9951

Respect --without-chroot correctly

./configure --without-chroot will configure tcpdump with "no" as the
value of chroot directory and cause tcpdump to fail with:

tcpdump: Couldn't chroot/chdir to 'no': No such file or directory

This patch makes ./configure to avoid chroot directory when called with
--without-chroot.
