SVN rev 219173 on 2011-03-02 09:53:13Z by netchild
MFC r215664:
By using the 32-bit Linux version of Sun's Java Development Kit 1.6
on FreeBSD (amd64), invocations of "javac" (or "java") eventually
end with the output of "Killed" and exit code 137.
This is caused by:
1. After calling exec() in multithreaded linux program threads are not
destroyed and continue running. They get killed after program being
executed finishes.
2. linux_exit_group doesn't return correct exit code when called not
from group leader. Which happens regularly using sun jvm.
The submitters fix this in a similar way to how NetBSD handles this.
I took the PRs away from dchagin, who seems to be out of touch of
this since a while (no response from him).
The patches committed here are from [2], with some little modifications
from me to the style.

MFC r215675:
Do not take the process lock. The assignment to u_short inside the
properly aligned structure is atomic on all supported architectures, and
the thread that should see side-effect of assignment is the same thread
that does assignment.
Use a more appropriate conditional to detect the linux ABI.
