Hello!

I just run a quick grep to see which files might be interesting.

We use ant-build-system in:
axoloti.scm *
bioinformatics.scm *
compression.scm *
icu4c.scm
java.scm *
libusb.scm *
music.scm *
textutlis.scm
uml.scm *
version-control.scm *
web.scm *
xml.scm

Only the ant-build system uses icedtea among build systems.

Icedtea is explicitly metioned in the ones maked with *, and:
kodi.scm
math.scm
ruby.scm

We have a definition in place where currently icedtea is defined to be
icedtea-7.
I guess we could just flip that to icedtea-8, and check what still works.
That would flip the version in the build system also, as it uses "icedtea".

Should I check which packages are affected in advance, or just go with the
build and see what does not work?
