RFR: 8144885: agent/src/os/linux/libproc.h needs to support Linux/SPARC builds

[Gerald Thornbrugh]

Hi David,

Yes, I believe this is a devkit issue.  Mikael and I have been working 
to get JDK9 building
in JPRT with the lab Linux/SPARC machines that use a devkit and this 
change was needed.
I will update the bug detailing this as a devkit issue.

Thanks!

Jerry
