Bug #6904: make -j all fails (sometimes)

[Shyouhei Urabe]

make -jは現在まともに動いていません。

http://travis-ci.org/#!/ruby/ruby/jobs/2194633

cp: cp: cp: cannot create regular file ../../.ext/common/openssl'cannot create regular file../../.ext/common/openssl': File exists: File existscannot create regular file `../../.ext/common/openssl': File existscp:

想像ですがGNU Makeが再帰的に動く場合の-jの挙動が理解されていないのではないかと思います(gmakeではサブディレクトリも並列で動く)。
