[Buildroot] [git commit] tn5250: fix static build with openssl

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=1a07750cc55b83730fc264dc6c35bb8efebd5bf4
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

OpenSSL needs libz. Use pkg-config to find dependencies.

Fixes:
http://autobuild.buildroot.net/results/95f/95f6df0d01e4944ecd84e830e2bbd8389e1d3e3d/
http://autobuild.buildroot.net/results/432/432b1fdec1e6282d51ba1d859c0f4ab9ed2a5efc/
http://autobuild.buildroot.net/results/d6a/d6a7125c21b4f92b69bb9e30b05c4727eedb63ba/

and more.

[Thomas: use += instead of = when assigning <pkg>_CONF_ENV to avoid
future mistakes.]
