Added Minetest-0.4.4.
Add multilib gcc-4.6.

libquadmath seems to require that the bootstrap gcc be multilib too.
stdenv_32bit: Use gcc46_multi.

Fixes #80.
Update rubygems.

Particularly for rack-1.5.2, fixes CVE-2013-0263 and CVE-2013-0262.
curl: Update to version 7.29.0.

This version contains a security fix for CVE-2013-0249, for details please have
a look at:

http://curl.haxx.se/docs/adv_20130206.html

Thanks to @roconnor for pointing this out.

I'm pushing this to stdenv-updates because I'm not quite sure if it will break
other things because 7.29.0 is now non-blocking by default. Plus the security
vulnerability only affects IMAP, POP3 and SMTP protocol support.

Cherry-picked into master, this won't change stdenv.

gcc46_multi: Don't try to build on non-64-bit-linux
tex4ht: texLiveAggregationFun expects the texmf directory in $out, not $out/share
