Why did you removed PETSC_ARCH_NAME variable in makefiles?

[Barry Smith]

   Lisandro,

      That change will certainly NOT be reverted. PETSC_ARCH_NAME!  
what the heck kind of variable name is that?

      I need to understand the reason for PETSC_ARCH_NAME, then we can  
come up with some solution. What is the difference between
PETSC_ARCH_NAME and PETSC_ARCH? Is it only needed when --prefix is  
used (so PETSC_ARCH does not exist), if so, exactly why is it needed,  
the whole idea behind --prefix is to eliminate PETSC_ARCH, so why is  
it needed? How is PETSC_ARCH_NAME used?

   Barry
