Subject: [PATCH] tests: add a test for "resuming interrupted nanosleep"

* tests/restart_syscall.test: New test.
* tests/restart_syscall.expected: New file.
* tests/restart_syscall_unknown.expected: Likewise.
* tests/Makefile.am (TESTS): Add restart_syscall.test.
(EXTRA_DIST): Add restart_syscall.expected
(TEST_LOG_COMPILER): Change to "env".
(OS, ARCH, AM_TEST_LOG_FLAGS): Define.
and restart_syscall_unknown.expected.
