[Buildroot] [PATCH 0 of 2] strongswan: fix some autobuild failures

[Thomas De Schampheleire]

strongswan suffers from several autobuild failures. This series addresses
one of them: 'no rule to make target libtls.la'. While looking at it, I also
saw a missing host-pkgconf dependency, although I did not see this in any of
the autobuilds I checked.
