[petsc-dev] Error while building MAGMA from PETSc

Alternative way to handle this is:

>>>
#define HAVE_CUBLAS
#include "magma.h"
<<<

both in configure test - and petsc code that uses magma.h
[but I'm not sure if this is possible with configure/package.py]

Unfortunately since the compiler stuff is handled in such an arcane way in BuildSystem I don't know on what object this method should be called on. self?  self.framework? some compiler beasty? Anyways just tell him how call insertCompilerFlag() and the proper place to call it from within magma.py and everything will be fine.
