This bug can be reproduced in Ruby 1.8 as well.

Attached patch disables *context use on hurd.
Hurd implementation is not working yet and it's hard estimating whenever it will be.

Thanks.

1. Every workaroud patch should have a comment why it is needed any which version has a problem. Even though prior work don't.
2. defined(GNU) is unclear and confusable because a lot of people aren't familiar Hurd. So, it should be commented it's for GNU/Hurd.
3. Now, we have 5th exception (MS-Windows, NetBSD, Solaris, IA64, Hurd). So, it's a good time to move the check to configure.in.

Comment might be: "GNU/Hurd doesn't fully support {get,set,make,swap}context functions. Disabling their usage till support is implemented. More info at http://darnassus.sceen.net/~hurd-web/open_issues/glibc/#getcontext"
Feel free to rephrase as you prefer.

2. defined(GNU) is unclear and confusable because a lot of people aren't familiar Hurd. So, it should be commented it's for GNU/Hurd.

It's fine what you did in r43077.
