[petsc-dev] Enabling single precision for MUMPS and SUPERLU

[Hong Zhang]

Stefano :
I tested the patch with
single and double precision, double with '--with-scalar-type=complex'
All passed.
The patches are pushed to petsc-dev
(http://petsc.cs.iit.edu/petsc/petsc-dev/)

Thanks for your contribution!
Hong
