I don't have much experience with either Mesa or Ubuntu, but since the
original distro package seems to have the performance you expect, I
would recommend to take a look at how it's built. The original *source*
package is where I'd start on any distro. Regardless of the package
manager, the source package should include a build "recipe" with
specific compile options/flags.

As a bonus, if you go down this path, you end up with a binary package
that can replace the distro package, and you can use the default
package manager on your system (dpkg in your case). When the distro
eventually pulls in an even newer version of the package than the one
you compile, your manually compiled version of the library will be
replaced seamlessly.
