【Issue#771 Issue#1179 Issue#1143 動作確認】
□ テスト内容
各 Issue は以下の理由により、一括して対応した。
・ Issue#771 は ptrace のスレッドサポートである。
・ Issue#1179 は PTRACE_ATTACH の不具合対応であるが、スレッドの PTRACE_ATTACH
対応が Issue#771 に含まれるため、一括して対応することにした。
・ Issue#1143 は wait4 の __WALL フラグサポートであるが、スレッドの wait4 対応

5. wait4 で __WALL フラグ、__WCLONE フラグが正しく機能することを確認する。
CT771T037 wait4 のフラグに __WALL, __WCLONE 共に指定しないとき、pid に
子プロセスを指定してエラーにならないこと
CT771T038 wait4 のフラグに __WALL, __WCLONE 共に指定しないとき、pid に

□ 実行手順
$ make test
McKernelのインストール先や、OSTEST, LTPの配置場所は、 $HOME/.mck_test_config
を参照する。.mck_test_config は、McKernel をビルドした際に生成される
mck_test_config.sample ファイルを $HOME にコピーし、適宜編集すること。
また、C771.sh の以下の指定を適宜変更すること。
GDBBUILDDIR= GDB 構築したパス ($HOME にて gdb を src.rpm から構築している
場合は変更不要)
gdb のテストケースでは、dejagnu パッケージに含まれる runtest コマンドを使用
する。システムにインストールされていない場合は、予めインストールすること。
□ 実行結果
C771.txt 参照。
すべての項目をPASSしていることを確認。
