Thanks for the offer, and for the patch!

IMO, "the more the merrier".  So yeah, Solaris 11 buildslaves are
absolutely welcome.

Oh, cool, I saw your comment regarding my patch on the bug.  I'm happy
it helps to solve other problems.

Right.  Until I implement a way to enable only a subset of tests from
our testsuite, I agree that it's not a good idea to have builds taking
that long to finish.

Sorry about that.

The "arch" field is indeed unused.  The initial plan was to use it to
offer some filtering capabilities in the web interface, but that's been
replaced by "tags".

The "tags" filter is just a collection of tags that are used to
categorize the builders.  If you go to
<https://gdb-build.sergiodj.net/waterfall>, at the top of the page
you'll see a "Tags:" header, with a bunch of tags.  You can use them to
selectively display just the builders associated with a certain tag.
For example, if you want to list the x86_64 builders, you'd go to
<https://gdb-build.sergiodj.net/waterfall?tag=x86_64>.

There are two "special" tags: "MAIL" and "TEST".  When a builder is
marked as "MAIL", the BuildBot master will send e-mail notifications
about it to gdb-testers/gdb-patches.  If it's marked as "TEST", then all
e-mail notifications are supressed.  I just mark a builder as "TEST" if
it proves to unstable (i.e., when GDB fails to compile on it because of
some problem with the builder itself).  I think it makes sense to mark
your builders as "MAIL", since they're relatively stable, from what you
said.

I'll have to contact you in private in order to give the password
necessary for connection to the BuildBot master.  I'll also apply your
patch now and enable the builders, so all it's left for you is to start
them on your side.

Thank you very much again for your contribution!
