Yes, this seems like a good idea.

Do you mean that the shared binaries that end up in the JRE directory
are not stripped and that stripping them gets rid of all these
references?  (You could test this by copying the binaries from the store
and stripping them manually.)

The icedtea packages use the gnu-build-system, so I would expect them to
be stripped by default.

Sounds good to me.

Thanks for working on this, Gábor!
