Project makefile is not parallel make safe.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run make -j 4 (anything > 3 will cause failure)
2. Observe errors about dhry_1.o or dhry_2.o files.

What is the expected output? What do you see instead?

Project should compile without error using parallel make. Instead, project 
fails to compile due to race conditions in the construction and deletion of  
the dhry_1.o and dhry_2.o files.

What version of the product are you using? On what operating system?

All versions as far back as 4.0.1 (at least, probably always). Linux.

Please provide any additional information below.

Attached is a patch file to change the dhry2reg target to compile its versions 
of the dhry_1.o and dhry_2.o files to dhry_1_reg.o and dhry_2_reg.o so that the 
dhry2 target doesn't overwrite them.

I'll take a look and see if these changes cause any issues. If all looks well 
I'll integrate the change into UnixBench.

I added the patch, recompiled on Ubuntu Lucid 2.6.32x kernel, and ran Unixbench 
with -c 16 and all ran well. Let me check with Ian and if he's ok I'll bump the 
version to 5.1.3 and push it.

Ok, I integrated the patch and rev'd UnixBench to 5.1.3. Please test it and let 
me know if that works for you.
