With some simple changes, our devkit scripts can be made to generate

legacy devkits used by the traditional linux-arm profiles.
I'm not at all clear what this is providing or for whom. The legacy
linux-arm-vfp-hflt requires pointers to the X11R6 installation to
build. The linux-arm32 jib-profile has none, but instead lists
freetype as being bundled. ??
The target audience here is mainly Erik and me (and the Hotspot
engineers who have requested a simple way to build the arm port). This
provides us with an up-to-date, standard configured, devkit for building
arm-32.
In contrast to the legacy jib profile, we now have a devkit that is
build according to our standard, so configure need a minimal amount of
flags (hence no X11 flags). The bundled freetype is to simplify things;
we now have a version of freetype included in the OpenJDK source, and
it's by far the easiest to use it, rather than to include it in the
devkit, but this is not enabled by default on linux-arm.
I hope that answers your questions!
Yes - thanks. I'm not sure the legacy jib profile serves any purpose now
- or even if it still builds.
