Correction: support for Haiku not upstreamed into GCC

A necessary correction to an earlier post: support for Haiku has not been upstreamed into GCC. From the Haiku development mailing list:

It is definitely our goal to get Haiku's GCC toolchain upstream, and that commit does indeed nudge us a little in that direction... However it's a small portion of a larger commit adding architecture support.

Good to have this cleared up.
