[Buildroot] [git commit] zeromq: add PGM/EPGM support

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=eaf746eb9e8b10d5ff5011a989014b3df4b31ddc
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This adds support for Pragmatic General Multicast protocol on raw
IP (PGM, RFC 3208) or UDP frames (EPGM) for use as zeromq reliable
multicast transport. The library relies on openpgm package to
implement the protocol itself.
