* Bump the LLVM revision used for GNUstep to 7, the minimum to support
the new ABI.
* GNUstep-back does not work with lld, so mark it to use Gold (BFD LD
doesn't seem able to link Objective-C things).
* Turn off some annoying debug logs in GNUstep back, which generate
several messages per second when you move the mouse. These should
never have been enabled in a release build anyway.
* Downgrade Cenon to 4.0.2. This was the last version to actually work
with GNUstep (the later ones use XCode >= 5 .xib files, which GNUstep
can't parse).
* Update gorm to git head. The current release doesn't work with the
new Objective-C ABI, but -head has the patches to fix it.
* Update PikoPixel and add it to the gnustep-app meta-package.
* Update the three core GNUstep packages to the latest release.
* Update gnumail and pantomime to the latest release and fix a linking
error with the new ABI.
* Update GNUstep FTP to the latest version.
