8d665ee166 arm: fix typos in makefile for ARM m5 util and link statically
1) fixes a typo for clean target libgemOpJni.so -> libgem5OpJni.so
2) addes jni_gem5Op.h to clean since it is added during make
3) links the m5 utility statically since it won't work on some images otherwise

cf56619b0c arm: use -march when compiling m5op_arm.S
Using arm-linux-gnueabi-gcc 4.7.3-1ubuntu1 on Ubuntu 13.04 to compiled
the m5 binary yields the error:

m5op_arm.S: Assembler messages:
m5op_arm.S:85: Error: selected processor does not support ARM mode `bxj lr'

For each of of the SIMPLE_OPs. Apparently, this compiler doesn't like the
interworking of these code types for the default arch. Adding -march=armv7-a
makes it compile. Another alternative that I found to work is replacing the
bxj lr instruction with mov pc, lr, but I don't know how that affects the
KVM stuff and if bxj is needed.

4153a76478 arm: Make libm5 a dependency of the m5 utility
The m5 utility wasn't relinked properly since libm5.a wasn't a
dependency of the utility. This changeset addresses that issue.

fdcfbda38d m5: Expose m5 pseudo-instructions to C/C++ via a static library
Updated the util/m5/Makefile.arm so that m5op_arm.S is used to create
a static library - libm5.a. Allowing users to insert m5
psuedo-instructions into their applications for fine-grained
checkpointing, switching cpus or dumping statistics. e.g.

#include <m5op.h>

void foo(){
	...
	m5_reset_stats(<delay>,<period>)
	m5_work_begin(<workid>,<threadid>);
	...
	m5_work_end(<workid>,<threadid>);
	m5_dump_stats(<delay>,<period>);
}

e4830ad2eb gem5ops: Implement Java JNI for gem5Ops
These ops allow gem5 ops to be called from within java programs like the following:
import jni.gem5Op;

public  class HelloWorld {

    public static void main(String[] args) {
        gem5Op gem5 = new gem5Op();
        System.out.println("Rpns0:" + gem5.rpns());
        System.out.println("Rpns1:" + gem5.rpns());
    }

    static {
        System.loadLibrary("gem5OpJni");
    }
}

When building you need to make sure classpath include gem5OpJni.jar:
javac -classpath $CLASSPATH:/path/to/gem5OpJni.jar HelloWorld.java

and when running you need to make sure both the java and library path are set:
java -classpath $CLASSPATH:/path/to/gem5OpJni.jar -Djava.library.path=/path/to/libgem5OpJni.so HelloWorld
