These scripts were never shipped to end users (the corresponding
install_linux.sh was only added to the instset in LO times,
see 117b3242) but were used
by QA and developers to install multiple Solaris builds
as non-root using getuid.so.

But the "archive" installation set can be used for the
same purpopse and doesn't require a custom script.
