Fix regression from #8108 (Mar 2023). Since that change, gocross has always been rebuilt on each run of ./tool/go (gocross-wrapper.sh), adding ~100ms. (Well, not totally rebuilt; cmd/go's caching still ends up working fine.) The problem was $gocross_path was just "gocross", which isn't in my path (and "." isn't in my $PATH, as it shouldn't be), so this line was always evaluating to the empty string: gotver="$($gocross_path gocross-version 2>/dev/null || echo '')" The ./gocross is fine because of the earlier `cd "$repo_root"` Updates tailscale/corp#21262 Updates tailscale/corp#21263 Change-Id: I80d25446097a3bb3423490c164352f0b569add5f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
