Fix broken link in Java 8 build instructions

[kgibm]

FreeType 2.5.3 has been moved to the freetype-old subfolder. Also changed to https.

Freetype is included in the jdk8 repo now, it doesn't need to be downloaded separately. We should fix the instructions to reflect that, although older versions would still need to download it.

Freetype is included in the jdk8 repo now, it doesn't need to be downloaded separately. We should fix the instructions to reflect that, although older versions would still need to download it.

Why would we keep parts of the instructions that no longer apply? If someone wants to build an older version, they should consult the instructions of the same vintage. I think we should just remove the advice to download freetype (for all platforms). As things stand, it advises that you download it, but the configure option that used to refer to where it was downloaded is no longer used (nor even available).

Ok, maybe I'll just leave the removal of freetype to you all. I started searching all the build instructions for freetype and there are some things that I'm not sure if they should be removed or not (e.g. --with-freetype-include).
