Issue Description
Following official installation instructions, cannot compile Go using Go 1.24.4 - all.bash compilation script errors because of a test failure.
Affected Versions
Actually running Go 1.24.4. Trying to compile Go 1.25.0 - 1.25.3.
What I Was Doing
Install Go 1.24 using apt. Clone git@github.com:golang/go. Check out go1.25.3 or any other version in 1.25.0-1.25.3. cd src/ then ./all.bash, to try to compile a newer version of Go, as per installation instructions.
Error Message Encountered

Hardware & Platform
