Bug 365686

After compiling a fresh version of valgrind 3.11.0 and running memcheck against an application, I noticed the "Process terminating with default action of signal 4 (SIGILL): dumping core" error.


Also, related or not, one thing to keep in mind is my configuration.
"./configure --target=arm-none-linux-gnueabi --host=arm-linux-gnueabi --prefix=/usr/sbin/valgrind CFLAGS=-static". 
That is the only configuration that seems to work.
However, --host should be set to something different because the machine used for cross-compiling is not an arm-processor. The problem is, if i change my configuration to 
"./configure --target=arm-none-linux-gnueabi --prefix=/usr/sbin CFLAGS=-static --host=x86_64-unknown-linux-gnu", it does not compile.
So, the questin is what should --host be set to?

Upon response, I will attach the entire debug output

Reproducible: Always

Steps to Reproduce:
1.configure valgrind 3.11.0 
2. compile
3. run valgrind against the app
