Bad news, it failed (see

I tried building it for i686 on my laptop and it failed similarly.

This bug report seems to be relevant, and it suggests bugs in the Perl
bindings of Subversion:

For now I’ve disabled three of the git-svn tests that were reported to
fail intermittently in commit c7699ebeb4233d81f294ff7e8b8eb3676119ae4a,
so that we can hopefully build Git more reliably.
