Why did you removed PETSC_ARCH_NAME variable in makefiles?

[Jose E. Roman]

Barry,

I think the use of PETSC_ARCH_NAME is motivated by a request I sent in  
December last year, see http://lists.mcs.anl.gov/pipermail/petsc-dev/2008-December/001120.html

We use it when configuring SLEPc with a prefix-based PETSc. If you  
remove this variable, we will have to think about an alternative way  
of supporting that case.
