mips64el-linux binary disables stack guard

[headius]

Apparently the mips64el-linux binary we have disables the "stack guard", causing Hotspot to complain thusly:

OpenJDK 64-Bit Server VM warning: You have loaded library /tmp/jffi4965776428901618408.so which might have disabled stack guard. The VM will try to fix the stack guard now.
SUREFIRE-859: It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Needs to be fixed, but perhaps this warning indicates that the JVM is working around it?
