Comment(by jhpalmieri):
Okay, the problem is this: if you build Sage but never run it, then the
script sage-location doesn't get run, so the file SAGE_ROOT/local/lib
/sage-location.txt doesn't get created. Then if you move or copy that
directory, the file isn't there, so sage-location thinks everything is
okay, so it doesn't rewrite the .la files.
(This is despite the comment in sage-location that the files in local/lib
get written "during the build". This is also not platform-specific: I
just built on sage.math, and there is no file sage-location.txt until Sage
gets run for the first time. I was also wondering why I wasn't seeing the
message "The Sage install tree may have moved..." at the start of the
upgrade, and this explains it.)
See #10162 for a follow-up; it's a one-liner.
