Subject: [PATCH 1/2] linux-user: assume __NR_gettid always exists

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

The gettid syscall was introduced in Linux 2.4.11. This is old enough

that we can assume it always exists and thus not bother with the

conditional backcompat logic.
