Old installation docs

[Jonathan Wakely]

https://gcc.gnu.org/install/ says:

"There are also some old installation instructions
<https://gcc.gnu.org/install/old.html>, which are mostly obsolete but still
contain some information which has not yet been merged into the main part
of this manual."

But the link shows an empty page (except for the automated footer). Is
there a redirect that got lost in the last sourceware server move?
