Subject: [PATCH] Fix `make install` from tarballs (#54143)

This reverts part of 67b8ac0
(https://github.com/JuliaLang/julia/pull/47596#discussion_r1128658139).
That change broke `make install` from tarballs due to building docs
again, which fails as there's no git repo (and also requires Internet
access to download UnicodeData.txt.

Fixes #54037.
