Why did you removed PETSC_ARCH_NAME variable in makefiles?

SLEPc can be setup with or without prefix, irrespective of whether  
PETSc is prefixed or not.

Since we need a PETSC_ARCH, one could set an arbitrary value of  
PETSC_ARCH, then configure (with or without prefix)+make+(make install).

If the user does not set PETSC_ARCH, then SLEPc's configure will tell  
the user to set PETSC_ARCH=unknown before invoking make.
