Subject: travis: macos: unlink all deps, then relink
X-Git-Tag: suricata-4.0.0-beta1~250
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1a7c5a01a1a6b2023e14d153f4d787e9e5ad68ee;p=thirdparty%2Fsuricata.git

travis: macos: unlink all deps, then relink

Kind of ugly, but first unlink all dependencies then install.
The deps that don't get an upgrade will remain unlinked, so
relink all dependencies as relinking an already linked dep
does not error out.
