[petsc-dev] Experimental GNU make build system

[Satish Balay]

Ok. The 'child_info_fork::abort:' error below is due to gnumake somehow
trying to parallelize 'CLINKER /home/balay/petsc.clone/arch-gmake/lib/libpetsc.so'?

I see the same if I replace it with 'AR'. [here I'm having to use '-j 1' for AR part]

I have a successful build with 'make -j 8' - and then 'make -j '1 to
recover from AR errors. And 'make test' is successful.

my hacky changes to get this working is below.
