Thanks for the suggestion.  Using a separate file is difficult in
this case because the file names are generated from the OS and CPU
types.  For example, the OI SPARC file is:

    openjdk/hotspot/src/os_cpu/solaris_sparc/vm/os_solaris_sparc.cpp

but the OI x86 file is:

    openjdk/hotspot/src/os_cpu/solaris_x86/vm/os_solaris_x86.cpp

There's also no nearby Makefile that I can use to reduce the compiler
optimization level.  Openjdk source is quite complicated.

It's quite possible that nobody else has attempted to build openjdk
with gcc on SPARC hardware.  Someone who understands stack overflow
with a SPARC CPU may be able to give me the information I need.  I'm
willing to do the rest of the work to get openjdk working.
